Book Description
Drawing on the work of internationally acclaimed experts in the field, Handbook of Item Response Theory, Volume Two: Statistical Tools presents classical and modern statistical tools used in item response theory (IRT). While IRT heavily depends on the use of statistical tools for handling its models and applications, systematic introductions and reviews that emphasize their relevance to IRT are hardly found in the statistical literature. This second volume in a three-volume set fills this void. Volume Two covers common probability distributions, the issue of models with both intentional and nuisance parameters, the use of information criteria, methods for dealing with missing data, and model identification issues. It also addresses recent developments in parameter estimation and model fit and comparison, such as Bayesian approaches, specifically Markov chain Monte Carlo (MCMC) methods.

Book Description
Drawing on the work of 75 internationally acclaimed experts in the field, Handbook of Item Response Theory, Three-Volume Set presents all major item response models, classical and modern statistical tools used in item response theory (IRT), and major areas of applications of IRT in educational and psychological testing, medical diagnosis of patient-reported outcomes, and marketing research. It also covers CRAN packages, WinBUGS, Bilog MG, Multilog, Parscale, IRTPRO, Mplus, GLLAMM, Latent Gold, and numerous other software tools. A full update of editor Wim J. van der Linden and Ronald K. Hambleton’s classic Handbook of Modern Item Response Theory, this handbook has been expanded from 28 chapters to 85 chapters in three volumes. The three volumes are thoroughly edited and cross-referenced, with uniform notation, format, and pedagogical principles across all chapters. Each chapter is self-contained and deals with the latest developments in IRT.

Book Description
The modeling of item response data is governed by item response theory, also referred to as modern test theory. The eld of inquiry of item response theory has become very large and shows the enormous progress that has been made. The mainstream literature is focused on frequentist statistical methods for - timating model parameters and evaluating model t. However, the Bayesian methodology has shown great potential, particularly for making further - provements in the statistical modeling process. The Bayesian approach has two important features that make it attractive for modeling item response data. First, it enables the possibility of incorpor- ing nondata information beyond the observed responses into the analysis. The Bayesian methodology is also very clear about how additional information can be used. Second, the Bayesian approach comes with powerful simulation-based estimation methods. These methods make it possible to handle all kinds of priors and data-generating models. One of my motives for writing this book is to give an introduction to the Bayesian methodology for modeling and analyzing item response data. A Bayesian counterpart is presented to the many popular item response theory books (e.g., Baker and Kim 2004; De Boeck and Wilson, 2004; Hambleton and Swaminathan, 1985; van der Linden and Hambleton, 1997) that are mainly or completely focused on frequentist methods. The usefulness of the Bayesian methodology is illustrated by discussing and applying a range of Bayesian item response models.

Book Description
Using familiar concepts from classical measurement methods and basic statistics, Hambleton and colleagues introduce the basics of item response theory (IRT) and explain the application of IRT methods to problems in test construction, identification of potentially biased test items, test equating, and computerized-adaptive testing. The book also includes a thorough discussion of alternative procedures for estimating IRT parameters, such as maximum likelihood estimation, marginal maximum likelihood estimation, and Bayesian estimation in such a way that the reader does not need any knowledge of calculus to follow these explanations. Including step-by-step numerical examples throughout, the book concludes with an exploration of new directions in IRT research and development.

Book Description
The predominant model checking method used in Bayesian item response theory (IRT) models has been the posterior predictive (PP) method. In recent years, two new Bayesian model checking methods have been proposed that may be used as alternatives to the PP method. We refer to these as the prior-predictive posterior simulation (PPPS) method of Dey et al. (1998), and the pivotal discrepancy measure (PDM) method of Johnson (2007). These methods have shown to be effective in other Bayesian models, but have never been implemented with Bayesian IRT models. It is of practical interest to see if either of these two new methods will perform better than the PP method in assessing aspects of fit in an IRT model setting. In this dissertation, we compared the effectiveness of the PPPS and PDM model checking methods with the PP method in evaluating person fit in two-parameter normal ogive (2PN) IRT models, and overall model goodness-of-fit in 2PN testlet models. Two simulation studies were performed. The first study explored the performance of each method (PP, PPPS, and PDM) in assessing person fit, or the goodness-of-fit of an individual's set of test answers with the assumed Bayesian 2PN IRT model. Several classical person fit measures were employed under each method. We also introduced using the sum of squared Bayesian latent residuals as a person fit measure. Four different types of person miss-fit were taken from the literature, and response data sets were simulated with certain examinee's responses following these violations. We found that for most of the measures, the PPPS and PDM methods outperformed the PP method in detecting the examinee's response patterns simulated to be aberrant under the model. In particular, the sum of squared Bayesian latent residuals showed to be a very effective measure under the PPPS method. The second simulation study compares the performance of the PP method and the PPPS method in assessing the overall goodness-of-fit of a Bayesian 2PN IRT model fitted to data generated under a Bayesian 2PN testlet model with equal variance across testlets. Under the PP method we used three goodness-of-fit measures based on biserial correlations that were previously employed for checking the goodness-of-fit of a three-parameter logistic (3PL) IRT model to 3PL testlet data. For use under the PPPS method, we introduced three new goodness-of-fit measures which are calculated from posterior values of the item discrimination parameters. Data sets were simulated under four different values of testlet variance, ranging from very low to fairly high. Looking at the detection rates under the PP method, we saw that the measures performed very poorly in detecting a lack of fit of the 2PN IRT model for all data values of testlet variance. The detection rates of the new measures under the PPPS method showed to be higher than those under the PP method. However, the measures under the PPPS method only showed descent power in detecting lack of fit for large values of data generating testlet variance.

Book Description
Drawing on the work of internationally acclaimed experts in the field, Handbook of Item Response Theory, Volume One: Models presents all major item response models. This first volume in a three-volume set covers many model developments that have occurred in item response theory (IRT) during the last 20 years. It describes models for different response formats or response processes, the need of deeper parameterization due to a multilevel or hierarchical structure of the response data, and other extensions and insights. In Volume One, all chapters have a common format with each chapter focusing on one family of models or modeling approach. An introductory section in every chapter includes some history of the model and a motivation of its relevance. Subsequent sections present the model more formally, treat the estimation of its parameters, show how to evaluate its fit to empirical data, illustrate the use of the model through an empirical example, and discuss further applications and remaining research issues.
