## Likelihood of the Etienne sampling formula

### Description

This function calculates the likelihood of the Etienne Sampling Formula, provided abundance data and parameter values.

### Usage

    	logLikelihood.ESF(theta, m, abund)

### Arguments

`theta` | Parameter value for the fundamental biodiversity number theta
`m` | Parameter value for migration
`abund` | Vector containing abundance data

### Value

Returns the LogLikelihood
