samp2_elife: Sample lifetime from excess lifetime model

In longevity: Statistical Methods for the Analysis of Excess Lifetimes

Sample lifetime from excess lifetime model

Description

Given parameters of a elife distribution, sampling window and birth dates with excess lifetimes, sample new observations; excess lifetime at c1 are sampled from an exponential distribution, whereas the birth dates are sampled from a jittered histogram-based distribution The new excess lifetime above the threshold are right-censored if they exceed c2.

Usage

samp2_elife(
  n,
  scale,
  shape,
  family = c("exp", "gp", "gomp", "gompmake", "weibull", "extgp", "gppiece",
    "extweibull", "perks", "beard", "perksmake", "beardmake"),
  xcal,
  c1,
  c2
)

Arguments

n	sample size
scale	scale parameter(s)
shape	shape parameter(s)
family	string; choice of parametric family
xcal	date at which individual reaches u years
c1	date, first day of the sampling frame
c2	date, last day of the sampling frame

Value

list with new birthdates (xcal), excess lifetime at c1 (ltrunc), excess lifetime above u (dat) and right-censoring indicator (rightcens).
