Investigating the Impact of Item Parameter Drift for Item Response Theory Models with Mixture Distributions
This study investigates the impact of item parameter drift (IPD) on parameter and ability estimation when the underlying measurement model fits a mixture distribution, thereby violating the item invariance property of unidimensional item response theory (IRT) models. An empirical study was conducted...
