#' Automobile
#'
#' This data set consists of three types of entities: (a) the specification of
#' an auto in terms of various characteristics, (b) its assigned insurance risk
#' rating, (c) its normalized losses in use as compared to other cars. The
#' second rating corresponds to the degree to which the auto is more risky than
#' its price indicates. Cars are initially assigned a risk factor symbol
#' associated with its price. Then, if it is more risky (or less), this symbol
#' is adjusted by moving it up (or down) the scale.  Actuarians call this
#' process "symboling".  A value of +3 indicates that the auto is risky, -3 that
#' it is probably pretty safe.
#'
#' The third factor is the relative average loss payment per insured vehicle
#' year.  This value is normalized for all autos within a particular size
#' classification (two-door small, station wagons, sports/speciality, etc...),
#' and represents the average loss per car per year.
#'
#' Note: Several of the attributes in the database could be used as a
#' "class" attribute.
