R: Summary Method Function for Objects of Class `loglm'

Summary Method Function for Objects of Class `loglm'

Usage

summary.loglm(object, fitted=F)

Arguments

`object`	a fitted loglm model object.
`fitted`	if `TRUE` return observed and expected frequencies in the result. Using `fitted = T` may necessitate re-fitting the object.

Description

Returns a summary list for log-linear models fitted by iterative proportional scaling using loglm.

Details

This function is a method for the generic function summary() for class loglm. It can be invoked by calling summary(x) for an object x of the appropriate class, or directly by calling summary.loglm(x) regardless of the class of the object.

Value

a list is returned for use by print.summary.loglm. This has components

formula the formula used to produce object
tests the table of test statistics (likelihood ratio, Pearson) for the fit.
oe if fitted = T, an array of the observed and expected frequencies, otherwise NULL.
