Negative binomial log-likelihood

Computes the log-likelihood for negative binomial (failures until r successes). L(r,p|x) = Σ

Usage

loglik_negbinom(r, p, x)

Arguments

r

Number of successes parameter (value object or fixed positive)

p

Success probability (value object), must be in (0,1)

x

Integer vector of failure counts

Value

A value object representing the log-likelihood
