Perform a Bayesian estimation of the Exploratory Deterministic Input, Noisy “And” Gate (EDINA) cognitive diagnostic model described by Chen et al. (2018).
Installation
You can install edina from CRAN using:
install.packages("edina")
Or, you can be on the cutting-edge development version on GitHub using:
if(!requireNamespace("devtools")) install.packages("devtools") devtools::install_github("tmsalab/edina")
Usage
To use the edina package, load it into R using:
library("edina")
From there, the EDINA model can be estimated using:
edina_model = edina(, chain_length = 10000)
To compute a model underneath different K attribute configured Q matrices, use:
edina_model = auto_edina(, k = 2:4, chain_length = 10000)
Note: Higher K configured Q matrices take longer to estimate.
Citing the edina package
To ensure future development of the package, please cite edina package if used during an analysis or simulation studies. Citation information for the package may be acquired by using in R:
citation("edina")
