R Dataset / Package boot / motor
Data from a Simulated Motorcycle Accident
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.
This data frame contains the following columns:
The time in milliseconds since impact.
The recorded head acceleration (in g).
A numeric column indicating to which of the three strata (numbered 1, 2 and 3) the observations belong.
An estimate of the residual variance for the observation.
vis constant within the strata but a different estimate is used for each of the three strata.
The data were obtained from
