Description

Computes predictive distribution for number of successes of future binomial experiment with a beta prior distribution for the proportion.

Usage

pbetap(ab, n, s)

Arguments

ab	vector of parameters of the beta prior
n	size of future binomial sample
s	vector of number of successes for future binomial experiment

Value

vector of predictive probabilities for the values in the vector s
