Computes Log-Likelihood of COM-Poisson

Share:

Description

Given a set of data, computes the log-likelihood of the data under the COM-Poisson distribution for values of the parameters.

Usage

1
com.loglikelihood(x, lambda, nu)

Arguments

x

matrix of count data

lambda

value of lambda parameter

nu

value of nu parameter

Details

The argument x should consist of a matrix where the first column is the level and the second column is the count for the corresponding level.

Value

The log-likelihood of the data.
