   times: The time in milliseconds since impact.

   accel: The recorded head acceleration (in g).

  strata: A numeric column indicating to which of the three
          strata (numbered 1, 2 and 3) the observations
          belong.

       v: An estimate of the residual variance for the
          observation.  `v' is constant within the strata
          but a different estimate is used for each of the
          three strata.

_S_U_M_M_A_R_Y_:

     The `motor' data frame has 94 rows and 4 columns.  The
     rows are obtained by removing replicate values of
     `time' from the dataset `mcycle'.  Two extra columns
     are added to allow for strata with a different residual
     variance in each stratum.  ~give succinct details here
