#' Extract model residuals
#' 
#' @description Extracts the residuals of a (standardized) major axis fit.
#' 
#' @details Residuals are calculated as y-bx-a for each group. These values are useful
#' in assumption checking, especially in constructing residual vs fitted value
#' plots.
#' 
#' @param object Object of class 'sma'.
#' @param \dots Further arguments ignored.
#' @return A vector of residuals.
