Abstract
An easily computed approximation to the resulting PSE-Levine equipercentile equating function is illustrated on data from a special study and compared to the results from the traditional equating functions. The special data set includes a criterion equating function, and the closeness of the PSE-Levine function to this criterion indicates that such hybrid equating functions may be useful in practice.
