In equate: Observed-Score Linking and Equating

#' Observed-Score Linking and Equating
#' 
#' 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.
