ASCAL [microform] : A Microcomputer Program for Estimating Logistic IRT Item Parameters / C. David Vale and Kathleen A. Gialluca.

ASCAL is a microcomputer-based program for calibrating items according to the three-parameter logistic model of item response theory. It uses a modified multivariate Newton-Raphson procedure for estimating item parameters. This study evaluated this procedure using Monte Carlo Simulation Techniques....
