Specifies the information required to fit a Negative Binomial generalized
linear model, with known
theta parameter, using
negative.binomial(theta = stop("'theta' must be specified"), link = "log")
The known value of the additional parameter,
The link function, as a character string, name or one-element
character vector specifying one of
identity, or an object of class
An object of class
"family", a list of functions and
expressions needed by
glm() to fit a Negative Binomial
generalized linear model.
