GDINA

The Generalized DINA Model Framework

A set of psychometric tools for cognitive diagnosis modeling based on the generalized deterministic inputs, noisy and gate (G-DINA) model by de la Torre (2011) and its extensions, including the sequential G-DINA model by Ma and de la Torre (2016) for polytomous responses, and the polytomous G-DINA model by Chen and de la Torre for polytomous attributes. 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. For tutorials, please check Ma and de la Torre (2020) , Ma and de la Torre (2019) , Ma (2019) and de la Torre and Akbay (2019) .

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 generalized multiple-strategy cognitive diagnosis models (experimental)
  • 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

Installation

To install this package from source:

  1. Windows users may need to install the Rtools and include the checkbox option of installing Rtools to their path for easier command line usage. Mac users will have to download the necessary tools from the Xcode and its related command line tools (found within Xcode’s Preference Pane under Downloads/Components); most Linux distributions should already have up to date compilers (or if not they can be updated easily).

  2. Install the devtools package (if necessary), and install the package from the Github source code.

# install.packages("devtools")
devtools::install_github("Wenchao-Ma/GDINA")

  • 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.
