apply_shift {heemod}

Apply a time shift to a survival distribution

Description

Apply a time shift to a survival distribution

Usage

apply_shift(dist, shift)

Arguments

dist

A survival distribution.

shift

A time shift to be applied.

Details

A positive shift moves the fit backwards in time. That is, a shift of 4 will cause time 5 to be evaluated as time 1, and so on. If shift == 0, dist is returned unchanged.

Value

A surv_shift object.

Examples

dist1 <- define_surv_dist(distribution = "gamma", rate = 0.25, shape = 3)
shift_dist <- apply_shift(dist1, 4)
compute_surv(dist1, 1:10)
compute_surv(shift_dist, 1:10)
