#' Model parameters for the GGompertz/NBD model are \code{r, alpha, beta, b and s}. \cr
#' \code{r}: shape parameter of the Gamma distribution of the purchase process.
#' The smaller \code{r}, the stronger the heterogeneity of the purchase process.\cr
#' \code{alpha}: scale parameter of the Gamma distribution of the purchase process.\cr
#' \code{beta}: scale parameter for the Gamma distribution for the lifetime process.\cr
#' \code{b}: scale parameter of the Gompertz distribution (constant across customers).\cr
#' \code{s}: shape parameter of the Gamma distribution for the lifetime process.
#' The smaller \code{s}, the stronger the heterogeneity of customer lifetimes.
