#' Print an object
#' @description This function prints information about the fitted model from a call to \code{\link{SMLE}()} or \code{\link{smle_select}()},
#' or about the simulated data from a call to \code{\link{Gen_Data}()}. The object passed as an argument to print is returned invisibly.

#' @param x Fitted object.

#' @param ... This argument is not used and listed for method consistency.
