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

likpois(lambda, x, log = FALSE)

## Arguments

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

## 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.

## Details

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

## Examples

likpois(x = rpois(n = 2, lambda = 4),
lambda = 4)#> [1] 0.02035637
