Multidimensional Item Response Theory Estimation: A computer program
Marek Libura · 1987
Abstract : The Mirte computer program, which provides estimates of item parameters and individuals' proficiencies (abilities) based on the multidimensional two-parameter logistic (M2PL) item response theory model, is described. The program uses a modified Newton-Raphson algorithm to iteratively estimate the parameters and proficiencies. The algorithm, use of the program, and some results based on simulated datasets are described.
