gibbscap1 {bayess} | R Documentation |
This function implements a regular Gibbs sampler associated with Chapter 5 for a two-stage capture recapture model with open populations, accounting for the possibility that some individuals vanish between two successive capture experiments.
gibbscap1(nsimu, n1, c2, c3, N0 = n1/runif(1), r10, r20)
nsimu |
number of simulated values in the sample |
n1 |
first capture population size |
c2 |
number of individuals recaptured during the second experiment |
c3 |
number of individuals recaptured during the third experiment |
N0 |
starting value for the population size |
r10 |
starting value for the number of individuals who vanished between the first and second experiments |
r20 |
starting value for the number of individuals who vanished between the second and third experiments |
N |
Gibbs sample of the simulated population size |
p |
Gibbs sample of the probability of capture |
q |
Gibbs sample of the probability of leaving the population |
r1 |
Gibbs sample of the number of individuals who vanished between the first and second experiments |
r2 |
Gibbs sample of the number of individuals who vanished between the second and third experiments |
