Data from a Simulated Motorcycle Accident
SUMMARY:
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.

DATA DESCRIPTION:
This data frame contains the following columns:
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.
