hazardcross_Weibull {survELtest}

Simulated survival data with crossing hazard functions from the Weibull distribution

Description

The data frame hazardcross_Weibull is obtained as follows. The survival time is generated from the Weibull model displayed as the solid and dashed lines in the right panel of Figure 1 in Chang and McKeague (2019). 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_Weibull

Format

The hazardcross_Weibull 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
