# Equation of the PMF of the METE spatial species abundance distribution

### Description

`metePi`

is a low level function that returns the spatial species abundance
distribution *Pi(n)* predicted by METE; vectorized in n

### Usage

1 | ```
metePi(n, la, n0)
``` |

### Arguments

`n` |
A vector giving abundances of each entry |

`la` |
The spatial Lagrange multiplier returned by |

`n0` |
Total abundance in area A0 |

### Details

See Examples

### Value

a numeric vector giving the probability of each entry in `n`
