#' Modified Simulation of two groups of normal bivariate distributions
#'
#' A dataset containing two groups of normal bivariate distributions with
#' diferent means and covariance matriz used to test the bpwpm2 model. Group 1
#' has 200 observations with mean (2,2) and covariance matrix (0.25, 0.35; 0.35,
#' 1). Group 2, 150 observations, with mean (4,4) and covariance matrix (1,
#' -0.24; -0.24, 0.64). Afterwards, the 13th right-most observation of Group 2
#' were manually re-coded to belong to Group 1 in order to have disjoined groups
#' to make the classification problem more intresting.
#'
#' @format A data frame 350 rows and 3 variables: \describe{ \item{Y}{factor,
#'   response variable used to codify the groups, also known as labels}
#'   \item{X1}{numeric, first covariable used for clasification}
#'   \item{X1}{numeric, second covariable used for clasification}}
