Description

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

Usage

## S3 method for class 'loglm'
summary(object, fitted = FALSE, ...)

Arguments

`object`	a fitted loglm model object.
`fitted`	if `TRUE` return observed and expected frequencies in the result. Using `fitted = TRUE` may necessitate re-fitting the object.
`...`	arguments to be passed to or from other methods.

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 = TRUE`, an array of the observed and expected frequencies, otherwise `NULL`.
