Summary Method Function for Objects of Class `negbin'

Usage

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

Arguments

object Fitted model object of class negbin inheriting from glm and lm. Typically the output of glm.nb.
dispersion as for summary.glm, with a default of 1.
correlation as for summary.glm.

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.

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 summary() for class negbin. It can be invoked by calling summary(x) for an object x of the appropriate class, or directly by calling summary.negbin(x) regardless of the class of the object.

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.
