#' Sample data set with a monotone missing pattern
#'
#' A simple data set with monotone missing pattern
#'
#' Sample data set with four predictors and a dependent variable. A
#' missing monotone pattern was generated in three predictors to
#' illustrate the gamlss imputation method.
#'
#' For the data generation process a parameter beta equal to
#' \code{c(1.3, .8, 1.5, 2.5)} and a predictor matrix \code{X <-
#' cbind(X.1, X.2, X.3, X.4)} are defined. Then, the sample data set
#' is created with the model \code{y ~ X.1 + X.2 + X.3 + X.4}.
