Error in check(itp) : object does not represent a K sample problem with censored data
...ded TRUE or FALSE as to whether a violent
offence was committed
4) recidivism$Event_nv coded TRUE or FALSE as to whether a
non-violent offence was committed
5) recidivism$group - there were 3 groups recorded as 1, 2 or 3
I encountered two problems:
a) when I tried to run the following: >
surv_test(Surv(recidivism$intDaysUntilFVPO, recidivism$Event_v) ~
recidivism$group, data = recidivism, distribution = "exact")
I received the following error message. I am unsure whether the
problem lies with the group variable, how I have set up the time
variables or there is something missing...
