#' Canadian Automobile Insurance Claims for 1957-1958
#'
#' The data give the Canadian automobile insurance experience for policy years
#' 1956 and 1957 as of June 30, 1959. The data includes virtually every
#' insurance company operating in Canada and was collated by the Statistical
#' Agency (Canadian Underwriters' Association - Statistical Department) acting
#' under instructions from the Superintendent of Insurance. The data given here
#' is for private passenger automobile liability for non-farmers for all of
#' Canada excluding Saskatchewan.
#'
#' @format A data frame with 20 observations on the following 6 variables:
#' \describe{
#'   \item{\code{Merit}}{Merit Rating:\cr
#' 3 - licensed and accident free 3 or more years\cr
#' 2 - licensed and accident free 2 years\cr
#' 1 - licensed and accident free 1 year\cr
#' 0 - all others}
#'   \item{\code{Class}}{1 - pleasure, no male operator under 25\cr
#' 2 - pleasure, non-principal male operator under 25\cr
#' 3 - business use\cr
#' 4 - unmarried owner or principal operator under 25\cr
#' 5 - married owner or principal operator under 25}
#'   \item{\code{Insured}}{Earned car years}
#'   \item{\code{Premium}}{Earned premium in 1000's\cr
#' (adjusted to what the premium would have been had all cars been written at 01 rates)}
#'   \item{\code{Claims}}{Number of claims}
#'   \item{\code{Cost}}{Total cost of the claim in 1000's of dollars}
#' }
#'
#' @details One could apply Poisson regression to the number of claims and gamma
#' regression to the cost per claim.
