GDINA

The Generalized DINA Model Framework

A set of psychometric tools for cognitive diagnosis modeling for both dichotomous and polytomous responses. Various cognitive diagnosis models can be estimated, include the generalized deterministic inputs, noisy and gate (G-DINA) model by de la Torre (2011) , the sequential G-DINA model by Ma and de la Torre (2016) , and many other models they subsume. Joint attribute distribution can be independent, saturated, higher-order, loglinear smoothed or structured. Q-matrix validation, item and model fit statistics, model comparison at test and item level and differential item functioning can also be conducted. A graphical user interface is also provided.

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 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

GDINA 2.0.7

  • bug fixed

GDINA 2.0

  • This is a major update including a large number of new features. The GDINA function has been largely rewritten for both flexibility and speed. Users are now allowed to fit MS-DINA model, Bugs models, and define models by providing design matrix and link functions. For joint attribute distribution, in addition to saturated and higher-order models, users are now allowed to fit independent model and loglinear model. Code for joint attribute distribution modelling has been restructured as well. Other major updates include model fit evaluation using M2 statistics and other limited information measures, item-level model selection using likelihood ratio test and score test, classification accuracy evaluation indices, bootstrap standard error estimation, etc.
  • Note that due to the major updates, some results from this version may be slightly different from those using the previous versions.
