Analytic Smoothing for Equipercentile Equating under the Common Item Nonequivalent Populations Design.

Kolen, Michael J.; Jarjoura, David

Psychometrika, v52 n1 p43-59 Mar 1987

A cubic spline method for smoothing equipercentile equating relationships under the common item nonequivalent populations design is described. Statistical techniques based on bootstrap estimation are presented for choosing an equating method/degree of smoothing. Smoothing decreases the estimate of random error but results in an increase in estimated systematic error. (Author/JAZ)
