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.

Direct, chain and average equating coefficients with standard
errors using IRT methods.
This package computes direct, chain and average (bisector)
equating coefficients with standard errors using Item Response
Theory (IRT) methods for dichotomous items.
