	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
