rpredBB: The Beta-Binomial Predictive Distribution

In vgharris3/predictiveInference: Predictive Inference Tools for Researchers

The Beta-Binomial Predictive Distribution

Description

rpredBB returns a random sample of size n from the Beta-Binomial predictive probability distribution computed from s observed successes out of a sample of size N, M future observations, and user input shape parameters for Beta prior on Pr(success)

Usage

rpredBB(S, N, t, M, alpha = 1, beta = 1)

Arguments

S	desired random sample size
N	number of observed independent binary variables
t	number of observed successes out of N observations
M	number of future observations for which prediction is desired
alpha	shape factor for prior Beta distribution on theta
beta	rate factor for prior Beta distribution on theta

Value

random sample of size n from the Beta-Binomial predictive probability distribution
