Summary Method Function for Objects of Class negbin

DESCRIPTION:

Identical to summary.glm, but with three lines of additional output: the ML estimate of theta, its standard error, and twice the log-likelihood function.

USAGE:

summary.negbin(object, dispersion = 1, correlation = T)
summary(object, dispersion = 1, correlation = T)

REQUIRED ARGUMENTS:

object
Fitted model object of class negbin inheriting from glm and lm. Typically the output of glm.nb.

OPTIONAL ARGUMENTS:

dispersion
as for summary.glm, with a default of 1.
correlation
as for summary.glm.
...
arguments passed to or from other methods.

VALUE:

As for summary.glm; the additional lines of output are not included in the resultant object.

SIDE EFFECTS:

A summary table is produced as for summary.glm, with the additional information described above.

DETAILS:

summary.glm is used to produce the majority of the output and supply the result. This function is a method for the generic function for class negbin. It can be invoked by calling for an object x of the appropriate class, or directly by calling regardless of the class of the object.
