Computes the expected vocabulary size of a LNRE model (Baayen, 2001) at sample size N.
EV(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 expected vocabulary size E[V(N)] is the expected number of
types at sample size N, according to the LNRE model model
(see Baayen, 2001).
a numeric vector of the same length as N
