#'   \item{YearMonth}{(factor): The date (YearMonth-YYYY-MM) of weaning.}
#'   \item{litterorder}{(factor): The parity, or litter birth order based on dam, is provided as a factor.}
#'   \item{litternum}{(integer): The litter number (litterorder - 1) is provided as an integer, where the first litter is 0, and each subsequent litter is numbered starting at 1.}
#'   \item{First_Litter}{(integer): A binary variable taking the values 0 or 1, indicating whether it is the first litter born to the given dam.}
