hazardcross {survELtest}

Simulated survival data with crossing hazard functions from the piecewise exponential distribution

Description

The data frame hazardcross is obtained as follows. The survival time is generated from the piecewise exponential model displayed in the left column of Figure 1 in Chang and McKeague (2016). The censoring distributions (the same in each arm) is specified to be uniform with administrative censoring at t = 10, and a censoring rate of 25\% in the first group.

Usage

hazardcross

Format

The hazardcross is a data frame with 100 observations of 3 variables, and has the following columns:

• time the observed times to first remission and censoring times

• censor the censoring indicator

• group the grouping variable
