Mark D. Reckase - Multidimensional Item Response Theory
IRT models for binary response data usually assume a logistic curve for the probability of a 'correct answer' as a function of an underlying latent construct, ...
Estimation of a four-parameter item response theory model ByWe carry out a simulation study to evaluate the performance of the GH test to detect non-normality of the latent variable in unidimensional IRT model for binary. An item response theory analysis of problem-solving processes in ...A basic algorithmic pattern for learning IRT models is an alternating optimization procedure akin to EM algorithms. This is a classical approach taught in ... ASSESSING THE FIT OF UNIDIMENSIONAL IRT MODELS FOR ...POSITION SENSITIVE IRT. 3. A Position Sensitive IRT Mixture Model.
