For this dissertation, four item purification procedures were implemented onto the generalized linear mixed model for differential item functioning (DIF) analysis, and the performance of these item purification procedures was...
This study examined the effectiveness of the odds-ratio method (Penfield, 2008) and the multinomial logistic regression method (Kato, Moen, & Thurlow, 2009) for measuring differential distractor functioning (DDF) effects in comparison to...
Many studies have been conducted to evaluate the performance of DIF detection methods, when two groups have different ability distributions. Such studies typically have demonstrated factors that are associated with inflation of Type I...
The focus of this study is to consider random differential item functioning (DIF) for polytomous items from a multilevel (3 level) logistic regression perspective. Often, in educational studies, three levels with nested variables are...
Differential Item Functioning Identification Strategy for Items with Dichotomous Responses Using the Item Information Curve: A Weighted Area Method (WAM)
Frequently researchers base their decisions and interpretations on conclusions drawn from data analyses, but what happens when the data used in the analyses are collected from unreliable instruments or surveys? The instrument may include...
