gamllik: Log likelihood from the gamma distribution

Description

A function computing the log likelihood from the gamma distribution under an order restriction reduction

Usage

gamllik(structtime,structttot,structdeaths,time_die,ttot,deaths)

Arguments

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"

Value

log of the likelihood

Examples

# NOT RUN {
time_die <- c(0.05,0.08,0.38,0.41,0.64)
ttot <- c(9.2,5.8,52.1,5.8,40.0)
deaths <- c(1,1,1,1,1)
structtime <- c(0.05,0.64)
structttot <- c(9.2, 40.0)
structdeaths = c(1, 5)
gamllik(structtime,structttot,structdeaths,time_die,ttot,deaths)
# }
