PFS Survival Function from Piecewise Constant Hazards

PWCsurvPFS(t, h01, h02, pw01, pw02)

Arguments

t

(numeric)
study time-points.

h01

(numeric vector)
constant transition hazards for 0 to 1 transition.

h02

(numeric vector)
constant transition hazards for 0 to 2 transition.

pw01

(numeric vector)
time intervals for the piecewise constant hazards h01.

pw02

(numeric vector)
time intervals for the piecewise constant hazards h02.

Value

This returns the value of PFS survival function at time t.
