VV {UCS} | R Documentation |
Computes the variance of the vocabulary size of a LNRE model (Baayen, 2001) at sample size N.
VV(model, N)
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 |
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).
a numeric vector of the same length as N
