Likelihood of the Etienne sampling formula

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
