update_beta {grizbayr}

Update Beta

Description

Updates Beta Distribution with the Beta-Bernoulli conjugate prior update rule

Usage

update_beta(alpha, beta, priors = list())

Arguments

alpha

Double value for alpha (count of successes). Must be 0 or greater.

beta

Double value for beta (count of failures). Must be 0 or greater.

priors

An optional list object that contains alpha0 and beta0. Otherwise the function with use Beta(1,1) as the prior distribution.

Value

A tibble object that contains 'alpha' and 'beta'

Examples

update_beta(alpha = 1, beta = 5, priors = list(alpha0 = 2, beta0 = 2))
update_beta(alpha = 20000, beta = 50000)
