log_lik_neg_binom: Negative Binomial Log-Likelihood

Description

Negative Binomial Log-Likelihood

Usage

log_lik_neg_binom(x, lambda = 1, theta = 0)

Value

An numeric vector of the corresponding log-likelihoods.

Arguments

x

A non-negative whole numeric vector of values.

lambda

A non-negative numeric vector of means.

theta

A non-negative numeric vector of the dispersion parameters for the gamma mixing distribution. The variance for the resultant gamma-Poisson distribution is lambda + lambda^2 * theta.
