dist_ll-methods: The log-likelihood function

In poweRlaw: Analysis of Heavy Tailed Distributions

Description

This is generic function for distribution objects. This function calculates the log-likelihood for the current parameters and xmin value.

Usage

dist_ll(m)

## S4 method for signature 'conlnorm'
dist_ll(m)

## S4 method for signature 'conexp'
dist_ll(m)

## S4 method for signature 'conpl'
dist_ll(m)

## S4 method for signature 'conweibull'
dist_ll(m)

## S4 method for signature 'disexp'
dist_ll(m)

## S4 method for signature 'dislnorm'
dist_ll(m)

## S4 method for signature 'displ'
dist_ll(m)

## S4 method for signature 'dispois'
dist_ll(m)

Arguments

m	a distribution object.

Value

The log-likelihood

Note

This method does *not* alter the internal state of the distribution objects.
