Statistical Methods for Test Score Equating
Description
The equate package contains functions for non-IRT equating
under both random groups and nonequivalent groups with anchor
test designs. Mean, linear, equipercentile and circle-arc
equating are supported, as are methods for univariate and
bivariate presmoothing of score distributions. Specific
equating methods currently supported include synthetic, nominal
weights, Tucker, Levine observed score, Levine true score,
Braun/Holland, frequency estimation, and chained equating.
