Items in the library are K-12 science and engineering learning resources. Spatialization and visualization are accomplished through 2D interactive Sammon mapping of pairwise item similarity scores based on the joint occurrence of word bigrams. The 65 science teachers participating in the experiment were asked to search the library for curricular items they would consider using in conducting one or more teaching assignments. Results indicate that whereas the spatializations adequately capture the salient features of the library’s content and teachers actively use them, item retrieval rates, task-completion time and perceived utility do not significantly differ from the semantically poorer but easier to comprehend and navigate list-based representations. These results put into question the usefulness of the rapidly increasing supply of information spatializations.10aBIS10aSupply Chain1 aReitsma, Reindert1 aHsieh, Ping-Hung1 aDiekema, Anne1 aRobson, Robby1 aZarsky, Malinda uhttp://journals.sagepub.com/doi/abs/10.1177/147387161666919300615nas a2200157 4500008004100000245010700041210006900148260000900217300001200226490000700238653001700245100002100262700001900283700001700302856013800319 2015 eng d00aDecision Support for Unrelated Parallel-Machine Scheduling with Discrete Controllable Processing Times0 aDecision Support for Unrelated ParallelMachine Scheduling with D c2015 a475-4830 v3010aSupply Chain1 aHsieh, Ping-Hung1 aYang, Suh-Jenq1 aYang, Dar-Li u/biblio/decision-support-unrelated-parallel-machine-scheduling-discrete-controllable-processing-times01461nas a2200157 4500008004100000245007300041210006900114260000900183520091500192653000801107653001701115100002201132700002101154700001801175856011001193 2015 eng d00aEstimation and Visualization of Digital Library Content Similarities0 aEstimation and Visualization of Digital Library Content Similari c20153 aWe report on a process for similarity estimation and two-dimensional mapping of lesson materials stored in a Web-based K12 Science, Technology, Engineering and Mathematics (STEM) digital library. The process starts with automated removal of all information which should not be included in the similarity estimations followed by automated indexing. Similarity estimation itself is conducted through a natural language processing algorithm which heavily relies on bigrams. The resulting similarities are then used to compute a Sammon-map; i.e., a projection in n dimensions, the item-to-item distances of which best reflect the input similarities. In this paper we concentrate on specification and validation of this process. The similarity results show almost 100% precision-by-rank in the top three to five ranks.

When price limits are reached, the observed prices are truncated and the equilibrium prices are unobservable, which makes further financial analyses difficult. The model offers theoretically sound estimates of censored returns and is demonstrated via simulations to outperform existing approaches with respect to the estimates of model parameters, unconditional means, and standard deviations. The algorithm is applied to model stock and futures returns and results are consistent with the simulation outcomes.

It has been demonstrated that the distribution of large claims of several lines of insurance have Pareto-type tails. As a result, estimating the tail index, which is a measure of the heavy-tailedness of a distribution, has received a great deal of attention. Although numerous tail index estimators have been proposed in the literature, many of them require detailed knowledge of individual losses and are thus inappropriate for insurance data in partitioned form. In this study we bridge this gap by developing a tail index estimator suitable for partitioned loss data. This estimator is robust in the sense that no particular global density is assumed for the loss distribution. Instead we focus only on fitting the model in the tail of the distribution where it is believed that the Pareto-type form holds. Strengths and weaknesses of the proposed estimator are explored through simulation and an application of the estimator to real world partitioned insurance data is given.10aSupply Chain1 aIII, John, B.

A logit model incorporates explanatory variables from microstructure literature and reveals that the conditional probability of a price increase (decrease) increases significantly when the price approaches the upper (lower) price limit, in support of the magnet effect. Our approach recognizes when the magnet effect starts to emerge and identifies possible determinants of magnet effect. The probability of information-based trading has a significant impact on the magnet effect for lower price limits.

The method requires and employs the knowledge of an expert and accounts for uncertainty in parameter estimation. Both considerations are essential for the task at hand because the available data are typically scarce in extreme value analysis. In addition, we consider three-parameter Gamma priors for the parameter in the model and thus provide simple analytical solutions to several key elements of interest, such as the predictive moments of record value. As a result, the model enables practitioners to gain insights into the behavior of such predictive moments without concerning themselves with the computational issues that are often associated with a complex Bayesian analysis. A data set consisting of catastrophe losses occurring in the United States between 1990 and 1999 is analyzed, and the forecasts of next record loss are made under various prior assumptions. We demonstrate that the proposed method provides more reliable and theoretically sound forecasts, whereas the conditional mean approach, which does not account for either prior information or uncertainty in parameter estimation, may provide inadmissible forecasts.10aSupply Chain1 aHsieh, Ping-Hung u/biblio/data-analytic-method-forecasting-next-record-catastrophe-loss-000450nas a2200121 4500008004100000245005800041210005500099260002600154653001700180100002100197700001600218856009400234 2004 eng d00aOn Examining Asymmetric Behavior of Price Limit Moves0 aExamining Asymmetric Behavior of Price Limit Moves aToronto, Canadac200410aSupply Chain1 aHsieh, Ping-Hung1 aYang, Jimmy u/biblio/examining-asymmetric-behavior-price-limit-moves-000516nas a2200109 4500008004100000245010800041210006900149260002800218653001700246100002100263856012200284 2004 eng d00aTales from the Tails: Two of My Current Studies on Observations Residing in the Tails of a Distribution0 aTales from the Tails Two of My Current Studies on Observations R aCorvallis, 鶹ýc200410aSupply Chain1 aHsieh, Ping-Hung u/biblio/tales-tails-two-my-current-studies-observations-residing-tails-distribution-002820nas a2200169 4500008004100000245013900041210006900180260000900249300001400258490000700272520217500279653001402454653001702468100001502485700002102500856012902521 2003 eng d00aInterdependence and its Consequence in Distributor-Supplier Relationships: A Distributor Perspective Through Response Surface Approach0 aInterdependence and its Consequence in DistributorSupplier Relat c2003 a101 - 1120 vXL3 aInterdependence and its consequences in marketing channels have received substantial research attention, but two issues remain unresolved. First, the validity of the extant methods to measure interdependence has not been verified, and those methods have not been contrasted. Second, the impact of interdependence on an outcome variable is difficult to analyze and its potential to provide managerial insight hampered. To address those gaps, the authors first review prior approaches. The review of prior approaches raises key methodological and theoretical issues in measuring interdependence and analyzing its impacts, including the additivity of distributor and supplier dependences for measurement of interdependence and the nonlinear functional forms of dependences for the impact of interdependence.The authors use the response surface approach (RSA) and derive three managerial insights that can be garnered from its use: interdependence for the highest (lowest) level of an outcome, directions for change in interdependence, and change in outcome when receding from the ideal combination. They apply RSA to the relationship between interdependence and three outcome variablesdistributor commitment, bilateral communication, and supplier controlin industrial distributor”supplier relationships and contrast it with previous methods.
The empirical study results suggest that (a) distributors perceive differential effects of supplier dependence and distributor dependence on outcome variables and (b) highest magnitude and lowest asymmetry of interdependence do not lead to the highest distributor commitment or supplier control. From a distributor's standpoint, highest commitment and supplier control occur when distributor dependence is high and supplier dependence is modest. The following implications emerge: Distributor dependence and supplier dependence must be decoupled and treated separately. Distributor dependence can be encouraged and nurtured, while supplier dependence needs to be kept moderate. A supplier's too little or too great dependence on a distributor will deteriorate channel outcomes, at least from a distributor's point of view.

Using an improved, time series, cross-sectional regression model that accounts for both contemporaneous and firm-specific serial correlation, as well as the feedback between firm profitability and investments, our study compares the rate of return from a dollar investment on R&D to a dollar investment on fixed assets in pharmaceutical and chemical industries. We find positive associations of R&D intensity and all variables of firm performance (net margin, operating margin, sales growth, and market value). We find that an investment in R&D earns an operating margin return much higher than the industry cost of capital. We also find that the effect of an investment in R&D on the firm's market value is about twice as much the effect of an investment in fixed assets. These findings have implications for corporate investment strategies, indicating that additional R&D investment is more likely to provide a firm with a unique and sustainable competitive advantage.10aStrategy & Entrepreneurship10aSupply Chain1 aHsieh, Ping-Hung1 aMishra, C., S.1 aGobeli, Dave u/biblio/return-rd-versus-capital-expenditures-pharmaceutical-and-chemistry-industies-000533nas a2200121 4500008004100000245008900041210006900130260003600199653001700235100002100252700002100273856011700294 2003 eng d00aTales from the Tail: Robust Moment Estimation for Singly Censored Environmental Data0 aTales from the Tail Robust Moment Estimation for Singly Censored aSan Francisco, Californiac200310aSupply Chain1 aHsieh, Ping-Hung1 aCheng, Tsung-Chi u/biblio/tales-tail-robust-moment-estimation-singly-censored-environmental-data-001679nas a2200145 4500008004100000245011900041210006900160260000900229300001200238490000700250520110100257653001701358100002101375856013701396 2002 eng d00aAn Exploratory First Step in Teletraffic Data Modeling: Evaluation of Long-run Performance of Parameter Estimators0 aExploratory First Step in Teletraffic Data Modeling Evaluation o c2002 a263-2830 v403 aExamination of the tail behavior of a distribution F that generates teletraffic measurements is an important first step toward building a network model that explains the link between heavy tails and long-range dependence exhibited in such data. When knowledge of the tail behavior of F is vague, the family of the generalized Pareto distributions (GPDs) can be used to approximate the tail probability of F, and the value of its shape parameter characterizes the tail behavior. To detect tail behavior of F between two host computers on a network, the estimation procedure must be carried out over all possible combinations of host computers, and thus, the performance of the estimator under repeated use becomes the primary concern. In this article, we evaluate the long-run performance of several existing estimation procedures and propose a Bayes estimator to overcome some of the shortcomings. The conditions in which the procedures perform well in the long run are reported, and a simple rule of thumb for choosing an appropriate estimator for the task of repeated estimation is recommended.10aSupply Chain1 aHsieh, Ping-Hung u/biblio/exploratory-first-step-teletraffic-data-modeling-evaluation-long-run-performance-parameter-000493nas a2200109 4500008004100000245008400041210006900125260002500194653001700219100002100236856012600257 2002 eng d00aForecasting Next Record Catastrophic Property Losses Using Extreme Value Theory0 aForecasting Next Record Catastrophic Property Losses Using Extre aTaipei, Taiwanc200210aSupply Chain1 aHsieh, Ping-Hung u/biblio/forecasting-next-record-catastrophic-property-losses-using-extreme-value-theory-001472nas a2200145 4500008004100000245009100041210006900132260000900201300001200210490000700222520093200229653001701161100002101178856012701199 2001 eng d00aOn Bayesian Predictive Moments of Next Record Value Using Three-parameter Gamma Priors0 aBayesian Predictive Moments of Next Record Value Using Threepara c2001 a729-7380 v303 aA forecasting model of next record value proposed by Hill [1] assumes the underlying distribution F(x) is of an algebraic functional form with a shape parameter a for large x. That is, 1 - F(x) ?Cx-a, for large x. In this article, we extend his model by incorporating a three-parameter Gamma prior of a to derive analytical solutions of the predictive distribution and moments of X given that X is a new record value. These closed-form formulas can be represented as ratios of moments of Gamma distributions. We apply the proposed model to a real-life data set that consists of the insured property losses of 33 catastrophes caused by tropical storms in the United States in 1995. The example illustrates the importance of incorporating prior experience and accounting for uncertainty in parameter estimation when forecasting record values. Both considerations are the main ingredients in the development of the proposed model.10aSupply Chain1 aHsieh, Ping-Hung u/biblio/bayesian-predictive-moments-next-record-value-using-three-parameter-gamma-priors-000482nas a2200109 4500008004100000245007900041210006900120260002700189653001700216100002100233856011800254 2001 eng d00aDiscrepancy Assessment of Model Fitness Against Nonparametric Alternatives0 aDiscrepancy Assessment of Model Fitness Against Nonparametric Al aAtlanta, Georgiac200110aSupply Chain1 aHsieh, Ping-Hung u/biblio/discrepancy-assessment-model-fitness-against-nonparametric-alternatives-001439nas a2200145 4500008004100000245007300041210006900114260000900183300001200192490000700204520093600211653001701147100002101164856010801185 2001 eng d00aModeling the Frequency and Severity of Extreme Exchange Rate Returns0 aModeling the Frequency and Severity of Extreme Exchange Rate Ret c2001 a485-4990 v203 aRisk managers are often concerned about tail probabilities of asset return distributions, in particular the frequency and severity of extreme returns. In this article, we propose a model that integrates extreme value theory and point processes to model the frequency and severity of exchange rate returns. The proposed model is applied to daily spot exchange rate series and the parameters of interest, such as the tail index, the mean size and rate of occurrence of extreme returns, are estimated using maximum likelihood estimation. We study the impact of recent currency crises on the frequency and severity of the series and find that, during 1995-9, the frequency of extreme daily Japanese yen-US dollar spot exchange rate returns increases twofold, and the time duration of high volatility persists longer for the Japanese yen series than for the Swiss franc and Danish krone series.

Without specifying any particular distribution, the use of an algebraic functional form Cx to approximate the tail behavior of the distributions in the class was demonstrated. Norwegian fire insurance data were examined, and the algebraic functional form was applied to derive the expected loss of a reinsurance treaty that covers all losses exceeding a retention limit. It was shown that (1) the expected loss is insensitive to the parameter á for a high retention limit (e.g., a catastrophe treaty), and (2) with a low retention limit (e.g., a largest claim treaty), a reliable estimate of the parameter á and a sound judgment on the maximum potential loss of the treaty could provide useful and defensible summary statistics for pricing the treaty. Thus, when dealing with the losses of certain reinsurance treaties, it was concluded that knowledge of a specific probability distribution is not critical, and the summary statistics derived from the model are robust with respect to a large class of loss distributions.10aSupply Chain1 aHsieh, Ping-Hung u/biblio/robustness-conditional-moments-application-premium-calculation-reinsurance-treaties-100573nas a2200133 4500008004100000245009400041210006900135260003000204653001700234100002100251700002400272700002200296856012100318 2000 eng d00aThe Returns to R&D and Capital Expenditures in the Pharmaceuticals and Chemicals Industry0 aReturns to RD and Capital Expenditures in the Pharmaceuticals an aSeattle, Washingtonc200010aSupply Chain1 aHsieh, Ping-Hung1 aMishra, Chandra, S.1 aGobeli, David, H. u/biblio/returns-rd-and-capital-expenditures-pharmaceuticals-and-chemicals-industry-000520nas a2200109 4500008004100000245010200041210006900143260003000212653001700242100002100259856013000280 1999 eng d00aRobustness of Conditional Moments: An Application to Premium Calculation for Reinsurance Treaties0 aRobustness of Conditional Moments An Application to Premium Calc aBaltimore, Marylandc199910aSupply Chain1 aHsieh, Ping-Hung u/biblio/robustness-conditional-moments-application-premium-calculation-reinsurance-treaties-201102nas a2200145 4500008004100000245004000041210004000081260000900121300001200130490000600142520069100148653001700839100002100856856007900877 1999 eng d00aRobustness of Tail Index Estimation0 aRobustness of Tail Index Estimation c1999 a318-3320 v83 aThe implementation of the Hill estimator, which estimates the heaviness of the tail of a distribution, requires a choice of the number of extreme observations in the tails, $r$, from a sample of size $n$, where $2 \leq r+1 \leq n$. This article is concerned with a robust procedure of choosing an optimal $r$. Thus, an estimation procedure, $\delta_s$, based on the idea of spacing statistics, $H^{(r)}$, is developed. The proposed decision rule for choosing $r$ under the squared error loss is found to be a simple function of the sample size. The proposed rule is then illustrated across a wide range of data, including insurance claims, currency exchange rate returns, and city size.10aSupply Chain1 aHsieh, Ping-Hung u/biblio/robustness-tail-index-estimation-0
