samp2_elife: 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
)

Value
