#' @details
#' 
#' Eha enhances the recommended \pkg{survival} package in several ways, 
#' see the description. The main applications in mind are demography and 
#' epidemiology. For standard Cox regression analysis the function 
#' \code{\link{coxph}} in \pkg{survival} is still recommended. The function 
#' \code{\link{coxreg}} in \pkg{eha} in fact calls coxph for the standard kind 
#' of analyses.
