| neg.binom {mgcv} | R Documentation |
Specifies the information required to fit a Negative Binomial Generalized
Additive Model, with known or unknown theta parameter, using
gam() and gam.nbut(). The code is a minor modification of
negative.binomial from library(MASS).
neg.binom(theta=NA, link="log")
theta |
The known value of the additional parameter, theta, or NA
if this is unknown.
|
link |
The link function. Currently must be one of log, sqrt or identity.

A list of functions and expressions needed by gam() to fit a
generalised additive mode with Negative Binomial errors.
