gdina package for cognitively diagnostic

We have hosted the application gdina package for cognitively diagnostic in order to run this application in our online workstations with Wine or directly.

Quick description about gdina package for cognitively diagnostic:

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 generalized multiple-strategy cognitive diagnosis models (experimental). Estimating the diagnostic tree model (experimental). Estimating multiple-choice models. 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.

Features:

• Detect differential item functioning using Wald and likelihood ratio test
• Simulate data based on all aforementioned CDMs
• Provide graphical user interface for users less familiar with R
• Estimate multiple-choice models
• Validate Q-matrix under the general model framework
• Evaluate absolute and relative item and model fit

Programming Language: R.
