loopcuts {RPEXE.RPEXT} | R Documentation |
A function that iterates to compute the p-values from the backward elimination procedure (Han et al. 2014)
loopcuts(time,censor,cuttimes,mono)
time |
a sequence of time |
censor |
a vector indicating censored or not at the given times, 0 = censored; 1 = uncensored |
cuttimes |
unique, sorted, possible times to make the cuts, including 0 and the ending time |
mono |
0: 2-sided hypothesis: H0: lam1 is equal to lam2; H1: lam1 is not equal to lam2 1: 1-sided hypothesis: H0: lam1 is greater than or equal to lam2; H1: lam1 is less than lam2 2: 1-sided hypothesis: H0: lam1 is less than or equal to lam2; H1: lam1 is greater than lam2 |
the times in the backward elimination procedure and the corresponding p-values for each change-point in the iteration
