Given a fitted cp model (survreg object), generate random
pda and pdb parameters or random persistence times.
NOTE: This function is likely to move to call GenEst's rcp in future.
This will not change the results, but the GenEst version is more nicely
coded and keeping some coherence among the models is helpful.
sim_cp0(cpmodel, nsim, option = "parms")answer
Fitted cp model ((survreg object))
Number of simulation draws
option = "parms" returns random draws of parameters from
the fitted model; option != "parms" returns random draws of carcass
persistence times
