likpois: Poisson Log Likelihood Function

In BenBarnard/likelihoodExplore: Likelihood Exploration

Description

The log likelihood of a Poisson density with data, x, lambda parameter.

Usage

likpois(lambda, x, log = FALSE)

Arguments

lambda	vector of (non-negative) means.
x	vector of (non-negative integer) quantiles.
log	logical; if TRUE, probabilities p are given as log(p).

Details

The log likelihood is the log of a function of parameters given the data.

Value

A numeric scalar for the log likelihood of the Poisson density given the data where lambda can be held constant or if vector were given vector will be returned.

Examples

likpois(x = rpois(n = 2, lambda = 4),
        lambda = 4)
