Description
Contains methods for observed-score linking
and equating under the single-group, equivalent-groups,
and nonequivalent-groups with anchor test(s) designs.
Equating types include identity, mean, linear, general
linear, equipercentile, circle-arc, and composites of
these. Equating methods include synthetic, nominal
weights, Tucker, Levine observed score, Levine true
score, Braun/Holland, frequency estimation, and chained
equating. Plotting and summary methods, and methods for
multivariate presmoothing and bootstrap error estimation
are also provided.
