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")
install.packages("variationalDCM", repos = c('https://khijikata.r-universe.dev', 'https://cloud.r-project.org'))
The following groups of models are currently supported:
This package was developed as part of the project supported by JST, PRESTO Grant Number JPMJPR21C3, Japan and JSPS KAKENHI Grant Number 21H00936.
