pID: Produce the posteriors for P(ID_L_i = ID_R_j) from the...

In benaug/SPIM: This package contains MCMC algorithms in R and (some) Rcpp for various Spatial Partial Identity Models. Prospective users should email Ben before using.

Description

This function produces the posterior that left individual X is right individual Y. For complete identity individuals, left individual X = right individual X with probability 1.

Usage

pID(data, ID_Lout, ID_Rout, swapped = FALSE)

Arguments

data	a list produced by sim2side or in the same format
ID_Lout	the M x niter posterior of ID_L
ID_Rout	the M x niter posterior of ID_R
swapped	TRUE if mcmc2side swapped L and R sides before MCMC sampling, FALSE otherwise

Value

a list with elements pIDL and pIDR, which are also lists. Element X of pIDL corresponds to left individual X and contains the right individuals it was matched with on at least one MCMC iteration and the posterior for each match. Similarly for pIDR.
