pdarroch {bayess} R Documentation

## Posterior probabilities for the Darroch model

### Description

This function computes the posterior expectation of the population size for a two-stage Darroch capture-recapture experiment (Chapter 5) under a uniform prior on the range (0,400).

### Usage

pdarroch(n1, n2, m2)


### Arguments

 n1 size of the first capture experiment n2 size of the second capture experiment m2 number of recaptured individuals

### Details

This model can be seen as a conditional version of the two-stage model when conditioning on both sample sizes n_1 and n_2.

### Value

numerical value of the posterior expectation

pcapture
for (i in 6:16) print(round(sum(pdarroch(22,43,i)*1:400)))
