Generalized Additive Partial Mastery Cognitive Diagnosis Models (GaPM-CDM)

Overview

An R package for fitting Generalized Additive (Ga-) and Additive Partial-Mastery Cognitive Diagnosis Models (aPM-CDM, Shang et al., AoAS 2021), using stochastic approximation (Zhang & Chen, 2022, Psychometrika).

Installation

You can install the development version of gapmCDM from GitHub with:

# install.packages("devtools")
