`PWCsurvOS(t, h01, h02, h12, pw01, pw02, pw12)`

## Arguments

- t
(`numeric`

)

study time-points.

(`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.
