gamllik {RPEXE.RPEXT} | R Documentation |
A function computing the log likelihood from the gamma distribution under an order restriction reduction
gamllik(structtime,structttot,structdeaths,time_die,ttot,deaths)
structtime |
change-point times to be used to compute the likelihood value |
structttot |
total time on test (ttot) between each time point and the previous time point (or 0) corresponding to structtime |
structdeaths |
number of deaths corresponding to structttot |
time_die |
all event and censoring times from small to large |
ttot |
total time on test corresponding to time_die |
deaths |
the number of deaths corresponding to "ttot" |
log of the likelihood
