#' standardize: Tools for Standardizing Variables for Regression in R.
#'
#' The \code{standardize} package provides tools for standardizing variables
#' prior to regression (i.e. placing all of the variables to be used in a
#' regression on similar scales).
#' When all of the predictors in a regression are on a similar scale, it makes
#' the interpretation of their effect sizes more comparable. In the case of
#' gaussian regression, placing the response on unit scale also eases
#' interpretation. Standardizing regression variables also has computational
#' benefits in the case of mixed effects regressions, and makes determining
#' reasonable priors in Bayesian regressions simpler. To view the package
#' vignette, call \code{vignette("using-standardize", package = "standardize")}.
#' To see the version history, call \code{standardize.news()}.
#'
#' The \code{\link{named_contr_sum}} function gives named sum contrasts to
#' unordered factors, and allows the absolute value of the non-zero cells in
#' contrast matrix to be specified through its \code{scale} argument. The
#' \code{\link{scaled_contr_poly}} function gives orthogonal polynomial
#' contrasts to ordered factors, and allows the standard deviation of the
#' columns in the contrast matrix to be specified through its \code{scale}
#' argument. The \code{\link{scale_by}} function allows numeric variables
#' to be scaled conditioning on factors, such that the numeric variable has
#' the same mean and standard deviation within each level of a factor (or the
#' interaction of several factors), with the standard deviation specified
#' through its \code{scale} argument.
#'
#' The \code{\link{standardize}} function creates a
#' \code{\link[=standardized-class]{standardized}} object whose elements
#' can be used in regression fitting functions, ensuring
#' that all of the predictors are on the
#' same scale. This is done by passing the function's \code{scale} argument
#' to \code{\link{named_contr_sum}} for all unordered factors (and also
#' any predictor with only two unique values regardless of its original class),
#' to \code{\link{scaled_contr_poly}} for all ordered factors, and to
#' \code{\link{scale_by}} for numeric variables which contain calls to the
#' function. For numeric predictors not contained in a \code{\link{scale_by}}
#' call, \code{\link[base]{scale}} is called, ensuring that the result has
#' standard deviation equal to the \code{scale} argument to
#' \code{\link{standardize}}. Gaussian responses are always placed on
#' unit scale, using \code{\link[base]{scale}} (or \code{\link{scale_by}} if
#' the function was used on the left hand side of the regression formula).
#' Offsets for gaussian models are divided by the standard deviation of the
#' raw response (within-factor-level if \code{\link{scale_by}} is used on
#' the response).
