pava_dfr function

PAVA order restriction under decreasing failure rate (DFR)

This function imposes the PAVA DFR order restriction by eliminating change-points violating the restriction

pava_dfr(time_die,ttot,deaths)

Arguments

• time_die: event times
• ttot: the total time on test (ttot) corresponding to the event times
• deaths: the number of deaths at each event time

Returns

time2: the event times after PAVA ttot2: the corresponding ttot deaths2 the corresponding number of deaths

Examples

data(pava_dfrd)
t_d = pava_dfrd[,1]
t = pava_dfrd[,2]
d = pava_dfrd[,3]
pava_dfr(t_d, t, d)
