Statistical Methods for Test Score Equating
Description
The equate package contains functions for
non-IRT equating under equivalent 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.
