BetaBinomialDistribution

BetaBinomialDistribution[α, β, n] represents a beta binomial mixture distribution with beta distribution parameters α and β, and n binomial trials.

Examples

Create a beta binomial distribution:

dist = BetaBinomialDistribution[2, 5, 10]

Compute mean and variance:

{Mean[dist], Variance[dist]}
