plotPosteriorN {dga} R Documentation

Plots Posterior Distribution of Nmissing

Description

Plots the model averaged posterior distribution of the total number of elements (the solid line) and the contribution to the posterior of each of the models (dotted lines)

Usage

plotPosteriorN(weights, N, main = NULL)


Arguments

 weights The output of BMAfunction. N N + Nmissing. Or, if you prefer, just Nmissing. The former shows the posterior distribution of the total population size; the latter shows the posterior distribution of the number of missing elements. main the title of the plot

A plot.

##### 3 list example from M & Y #######
Y <- c(0, 60, 49, 4, 247, 112, 142, 12)
Y <- array(Y, dim = c(2, 2, 2))

delta <- 1

Nmissing <- 1:300

logprior <- N * log(b) - (N + a) * log(1 + b) + lgamma(N + a) - lgamma(N + 1) - lgamma(a)
