## Variance of the Vocabulary Size of a LNRE Model (zm, fzm)

### Description

Computes the variance of the vocabulary size of a LNRE model (Baayen,
2001) at sample size *N*.

### Usage

VV(model, N)

### Arguments

`model` |
an object of class `"zm"` or `"fzm"` ,
representing a Zipf-Mandelbrot (ZM) or finite Zipf-Mandelbrot (fZM)
LNRE model |

`N` |
a vector of positive integers, representing sample sizes |

### Details

The variance *V[V(N)]* is computed according to Baayen (2001,
120f). See the `EV`

help page for some more information
on the vocabulary size *V(N)*.

### Value

a numeric vector of the same length as `N`
