CDM (version 1.0-0)

Cognitive Diagnosis Modeling

Description

Functions and example empirical (i.e., fraction subtraction) and artificial data for cognitive diagnosis modeling. This package implements parameter estimation procedures for the deterministic-input, noisy-and-gate (DINA) and deterministic-input, noisy-or-gate (DINO) models and procedures for analyzing data under these models. See package?CDM for an overview.
