A data frame with 3000 observations on the following 6 variables.
TL
the observed event or censoring time for the primary outcome, equal to min(T, C) where T is the time of the primary outcome and C is the censoring time.
DL
the indicator telling whether the individual was observed to have the event or was censored, equal to 1*(T<C) where T is the time of the primary outcome and C is the censoring time.
TS
the observed event or censoring time for the intermediate event, equal to min(TS, C) where TS is the time of the intermediate event and C is the censoring time.
DS
the indicator telling whether the individual was observed to have the intermediate event or was censored, equal to 1*(TS<C) where TS is the time of the primary outcome and C is the censoring time.
Z
a baseline covariate vector
treat
treatment indicator
