Some issues in item response theory
… assumption of local independence (LI) in item response theory (IRT) models in the first three chapters, and differential item functioning (DIF) in IRT in the last chapter. A new term ""conditional trivariance"" for three items is defined, which is a measurement of joint local dependence among …

Quantum-classical correspondence in response theory
… quantum dynamics is studied in the context of response theory. Thesis discusses the mathematical origin of time-divergence of classical response functions and explains the failure of classical dynamic perturbation theory. The method of phase space quantization and the method of semiclassical …

Contributions to Estimation in Item Response Theory
In the logistic item response theory models, the number of parameters tends to infinity together with the sample size. Thus, there has been a longstanding question of whether the joint maximum likelihood estimates for these models are consistent. The main contribution of this paper is the study of …

WISE BLOOD THROUGH THE LENS OF READER RESPONSE THEORY
… O’Connor is very rarely associated with reader response theory, its framework offers a way to more fully appreciate O’Connor as an author and <em>Wise Blood</em> as a novel while addressing aspects of critics’ confusion. The objective of this study is to consider a previously under-researched …

Parsimonious item response theory modeling with different link functions
Traditional item response theory (IRT) models assume a symmetric error distribution and rely on symmetric (logit or probit) link functions to model the response probabilities. However, this assumption does not always hold in item response data. To explore the possible benefits of alternate link …

Utilizing Multidimensional Item Response Theory to Examine Social Capital
… the use of mixed-format multidimensional item response theory (MIRT) analysis for assessing the latent factor structure of the Social Capital Rating Scale (SCRS). The rating scale, an instrument developed for measuring the parent involvement and the peer network of high school students, …

Some fundamental issues in item response theory with applications
The first part of this thesis, Chapter 2 through Chapter 4, explores procedures for assessing latent test dimensionality. In Chapter 2, the structure and theoretical properties of conditional item pair covariances given a latent composite are thoroughly investigated. Such information is useful …

Local Correlation Approaches and Coupled Cluster Linear Response Theory
… this work, we introduce some of the underlying theory behind such calculations and test the performance of several local correlation techniques for polarizabilities, optical rotations, and excited state properties. In general, when the computational cost is significantly reduced, the necessary …

ITEM RESPONSE THEORY ANALYSIS OF THE TOP LEADERSHIP DIRECTION SCALE
<p>Item response theory (IRT) offers several advantages compared to classical test theory (CTT) in providing additional information on psychometric qualities of the scale. My goal was to demonstrate the superiority of IRT as compared to CTT through two analyses of the Top Leadership Direction scale …

Some Issues in Weak Local Independence in Item Response Theory
A method of Pashley and Reese (in press) for simulating locally dependent data, whose item pair dependencies relate directly to local dependence assessment procedures is discussed. This method is extended to allow for the simulation of local dependence that varies in magnitude across the examinee …

Theory and applications of nonparametric regression in item response theory
… unrestrictive assumptions on the underlying item response theory model as both test length and sample size increase. A large deviation probability inequality is given for ordinal ability estimation. The mean squared error of kernel smoothed item characteristic curve estimates is studied and a …

Some theoretical and applied results concerning item response theory model estimation
It has long been part of the Item Response Theory (IRT) folklore that under the usual empirical Bayes unidimensional IRT modeling approach, the posterior distribution of examinee ability given test response is approximately normal for a long test. Under very general non-parametric assumptions, we …

An experimental analysis of a coding response theory of discrimination learning
… has proposed four functional rules for a coding response theory of discrimination learning. Two of these rules, 1) coding responses occur in the presence of experimental stimuli and produce discriminative stimulus consequences, and 2) code items are values or a particular stimulus dimension, were …

A comparison of kernel equating and item response theory true score equating
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] This study compares the accuracy of NEAT-design IRT true score equating (TIRT) and kernel equating (KE) in different conditions. The relative accuracy of three methods (Stocking-Lord transformation based TIRT (SL TIRT), …

An application of item response theory to language testing: Model-data fit studies
Even though the application of IRT to language testing has recently attracted much attention, no model-data fit research has been conducted to explore the appropriateness of IRT modeling in language testing. The tenability of the strong assumption of unidimensionality has not been studied …
