The data frame hazardcross is simulated from two groups of piecewise exponential
lifetime distributions with crossing hazard functions. The estimated survival functions remain ordered even when the estimated hazard
functions are crossed.
See supELtest for the application.
hazardcrossThe hazardcross is a data frame with 100 simulated observations of 3 variables,
and has the following columns:
time the survival time
censor the censoring indicator
group the grouping variable
