normpostpred: Posterior predictive simulation from Bayesian normal sampling model

Description

Given simulated draws from the posterior from a normal sampling model, outputs simulated draws from the posterior predictive distribution of a statistic of interest.

Usage

normpostpred(parameters,sample.size,f=min)

Value

simulated sample of the posterior predictive distribution of the statistic

Arguments

parameters

list of simulated draws from the posterior where mu contains the normal mean and sigma2 contains the normal variance

sample.size

size of sample of future sample

f

function defining the statistic

Examples

# finds posterior predictive distribution of the min statistic of a future sample of size 15
data(darwin)
s=normpostsim(darwin$difference)
sample.size=15
sim.stats=normpostpred(s,sample.size,min)
