This is the ‘Rat tumor data’ data from Dinse and Lagakos (1984). 112 female and 207 male rats. This data can be considered as a current status data where the time (T) from birth to the onset of the tumor is the main variable of interest but is never observed, but can only be guessed by the set of the death time (survtime) and the tumor indicator (tumor). Quotes are from Dinse and Lagakos (1984).
