Kernel Smoothing Approaches to Nonparametric Item Characteristic Curve Estimation.

Ramsay, J. O.

Psychometrika, v56 n4 p611-30 Dec 1991

Kernel smoothing methods for nonparametric item characteristic curve estimation are reviewed. A simulation with 500 examinees and real data from 3,000 records of the Graduate Record Examination illustrate the rapidity of kernel smoothing. Even when population curves are three-parameter logistic, simulation suggests no loss of efficiency. (SLD)
