GDINA Package for Cognitive Diagnosis Modelling

Project Status: Active ? The project has reached a stable, usable state and is being actively developed. Build Status CRAN_Status_Badge rpackages.io rank

How to cite the package:

Ma, W. & de la Torre, J. (2018). GDINA: The generalized DINA model framework.R package version 2.1. Retrived from https://CRAN.R-project.org/package=GDINA

Features of the package

  • Estimating G-DINA model and a variety of widely-used models subsumed by the G-DINA model, including the DINA model, DINO model, additive-CDM (A-CDM), linear logistic model (LLM), reduced reparametrized unified model (RRUM), multiple-strategy DINA model for dichotomous responses
  • Estimating models within the G-DINA model framework using user-specified design matrix and link functions
  • Estimating Bugs-DINA, DINO and G-DINA models for dichotomous responses
  • Estimating sequential G-DINA model for ordinal and nominal responses
  • Estimating the diagnostic tree model (experimental)
  • Modelling independent, saturated, higher-order, loglinear smoothed, and structured joint attribute distribution
  • Accommodating multiple-group model analysis
  • Imposing monotonic constrained success probabilities
  • Accommodating binary and polytomous attributes
  • Validating Q-matrix under the general model framework
  • Evaluating absolute and relative item and model fit
  • Comparing models at the test and item levels
  • Detecting differential item functioning using Wald and likelihood ratio test
  • Simulating data based on all aforementioned CDMs
  • Providing graphical user interface for users less familiar with R
