Studying Differential Item Functioning via Latent Variable Modeling: A Note on a Multiple-Testing Procedure 27 Aug 2013 | 03:08 am
This note is concerned with a latent variable modeling approach for the study of differential item functioning in a multigroup setting. A multiple-testing procedure that can be used to evaluate group ...
Effectiveness of Combining Statistical Tests and Effect Sizes When Using Logistic Discriminant Function Regression to Detect Differential Item Functio... 27 Aug 2013 | 03:08 am
The objective of this article was to find an optimal decision rule for identifying polytomous items with large or moderate amounts of differential functioning. The effectiveness of combining statistic...
A Comparison of Exposure Control Procedures in CATs Using the 3PL Model 27 Aug 2013 | 03:08 am
This study compares the progressive-restricted standard error (PR-SE) exposure control procedure to three commonly used procedures in computerized adaptive testing, the randomesque, Sympson–Hetter (SH...
Examining Differential Math Performance by Gender and Opportunity to Learn 27 Aug 2013 | 03:08 am
Although a substantial amount of research has been conducted on differential item functioning in testing, studies have focused on detecting differential item functioning rather than on explaining how ...

False Positives in Multiple Regression: Unanticipated Consequences of Measurement Error in the Predictor Variables 27 Aug 2013 | 03:08 am
Type I error rates in multiple regression, and hence the chance for false positive research findings, can be drastically inflated when multiple regression models are used to analyze data that contain ...
Essential Unidimensionality Examination for Multicomponent Scales: An Interrelationship Decomposition Approach 27 Jun 2013 | 03:24 am
A procedure for examining essential unidimensionality in multicomponent measuring instruments is discussed. The method is based on an application of latent variable modeling and is concerned with the ...
The Legacies of R. A. Fisher and K. Pearson in the Application of the Polytomous Rasch Model for Assessing the Empirical Ordering of Categories 27 Jun 2013 | 03:24 am
Assessments in response formats with ordered categories are ubiquitous in the social and health sciences. Although the assumption that the ordering of the categories is working as intended is central ...
