   -- Description
      This data set consists of two types of entities: (a) the
      specification of an auto in terms of various characteristics, (b)
      its assigned insurance risk rating.  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, -2 that it is probably pretty safe.
