#' Hidden Markov model for the biofam data
#'
#' A five-state hidden Markov model (HMM) fitted for the \code{\link[TraMineR]{biofam}} data.
#'
#' @format A hidden Markov model of class \code{hmm};
#' a left-to-right model with four hidden states.
#'
#' @details
#' The model is loaded by calling \code{data(hmm_biofam)}. It was created with the
#' following code:
#' \preformatted{
#' data("biofam3c")
#'
#' # Building sequence objects
#' marr_seq <- seqdef(biofam3c$married, start = 15,
#' alphabet = c("single", "married", "divorced"))
#' child_seq <- seqdef(biofam3c$children, start = 15,
#' alphabet = c("childless", "children"))
#' left_seq <- seqdef(biofam3c$left, start = 15,
#' alphabet = c("with parents", "left home"))
