WebAbstract A unidimensional latent trait model for responses scored in two or more ordered categories is developed. This “Partial Credit” model is a member of the family of latent trait models which share the property of parameter separability and so permit “specifically objective” comparisons of persons and items. WebThe five programs are used to run the one-parameter logistic (1PL)/partial credit model (PCM), two-parameter logistic (2PL)/generalized partial credit model (GPCM), and/or three-parameter logistic (3PL)/GPCM on two real data sets and 30 simulated data sets. convert ghs to vndWebDec 4, 2024 · Mplus supports both the Partial Credit Model (PCM) and the Generalized Partial Credit Model (GPCM).
