In variationalDCM: Variational Bayesian Estimation for Diagnostic Classification Models

variationalDCM

variationalDCM is an R package that performs recently-developed variational Bayesian inference for diagnostic classification models (DCMs), which are a family of statistical models for collecting, analyzing, and reporting diagnostic information in Education and Psychology.

You can install this package from CRAN at https://cran.r-project.org/package=variationalDCM. Alternatively, a development version can be installed using the devtools package:

if(!require(devtools)){
  install.packages("devtools")
}
devtools::install_github("khijikata/variationalDCM")

Models

The following groups of models are currently supported: - DINA model - DINO model - Multiple-choice-DINA model - Saturated DCM - Hidden Markov DCM
