summary.loglm {MASS} | R Documentation

## Summary Method Function for Objects of Class 'loglm'

### 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`.
