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.

h12

(numeric vector)
constant transition hazards for 1 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.

pw12

(numeric vector)
time intervals for the piecewise constant hazards h12.

Value

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