#' Glog transformation for linear models
#'
#' The function transforms the dependent variable of a linear model using the 
#' Glog transformation. 
#'
#' @param object an object of type lm. 
#' @return An object of class \code{trafo}. Methods such as 
#' \code{\link{as.data.frame.trafo}} and \code{\link{print.trafo}} can 
#' be used for this class.
