Likelihood-Based Item-Fit Indices for Dichotomous Item Response Theory Models.
Orlando, Maria; Thissen, David
Applied Psychological Measurement, v24 n1 p50-64 Mar 2000
Introduces new goodness-of-fit indices for dichotomous item response theory (IRT) models. Indices are based on the likelihoods of number-correct scores derived from the IRT model, and they provide a direct comparison of the modeled and observed frequencies for correct and incorrect responses for each number-correct score. Assesses these indices through simulation. (Author/SLD)
