In vgharris3/predictiveInference: Predictive Inference Tools for Researchers

The Poisson-Gamma Predictive Distribution

Description

rpredPG returns a random sample of size n from the Poisson-Gamma predictive probability distribution given observations obs~Poi(theta) and theta~Gamma(alpha,beta)

Usage

rpredPG(S, y, alpha = 1, beta = 1)

Arguments

S	desired random sample size
y	vector of (observed) Poisson-distributed counts
alpha	sum of counts from beta prior observations for gamma prior distribution on theta
beta	number of prior observations for gamma prior distribution on theta

Value

Poisson-Gamma cumulative predictive probability
