dpredBB: The Beta-Binomial Predictive Distribution

In vgharris3/predictiveInference: Predictive Inference Tools for Researchers

The Beta-Binomial Predictive Distribution

Description

dpredBB returns the predictive probability of x future successes out of M trials, given s observed successes out of a sample of size N, and user input shape parameters for Beta prior on Pr(success)

Usage

dpredBB(tpred, N, t, M, alpha = 1, beta = 1)

Arguments

tpred	vector of integers: number(s) of successes for which prediction is desired
N	number of observed independent binary variables
t	number of observed successes out of N observations
M	number of future observations (note tpred <= M)
alpha	first shape factor for prior Beta distribution on theta
beta	second shape factor for prior Beta distribution on theta

Value

Beta-Binomial predictive probability
