metePhi: Equation of the METE species abundance distribution

In cmerow/meteR: Fitting and Plotting Tools for the Maximum Entropy Theory of Ecology (METE)

Description

metePhi returns the species abundance distribution (Phi(n)) predicted by METE; vectorized in n

Usage

metePhi(n, la1, la2, Z, S0, N0, E0)

Arguments

n	the value (number of individuals) at which to calculate Φ
la1, la2	Lagrange multipliers
Z	partition function
S0	Total number of species
N0	Total number of individuals
E0	Total metabolic rate
