Small-Sample Equating with Log-Linear Smoothing.

Livingston, Samuel A.

Journal of Educational Measurement, v30 n1 p23-39 Spr 1993

The extent to which log-linear smoothing could improve the accuracy of common-item equating by the chained equipercentile method in small samples of examinees was investigated with responses from a 100-item test and 93,283 examinees. Smoothing reduced the sample size required for a given degree of accuracy. (SLD)
