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...
Structural equation modeling (SEM) refers to statistical analyses of the relationships among observed and latent variables based on hypothesized models. In reality, proposed models are rarely perfect, specification search is conducted to...
The Coupled Additive Multiplicative Noises (CAM) model is introduced as a stochastic volatility process to extend the classical Black-Scholes model. The fast Fourier transform (FFT) method is used to compute the values of the probability...
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...
When conducting a meta-analysis, it is common to find many collected studies that report regression analyses, because multiple regression analysis is widely used in many fields. Meta-analysis uses effect sizes drawn from individual...
