Fit Log-Linear Models by Iterative Proportional Scaling -- Internal function

loglm1 is an internal function used by loglm. It is a generic function dispatching on the data argument.

Keywords
internal
Usage
loglm1(formula, data, ...)

## S3 method for class 'xtabs': loglm1(formula, data, \dots)

## S3 method for class 'data.frame': loglm1(formula, data, \dots)

## S3 method for class 'default': loglm1(formula, data, start = rep(1, length(data)), fitted = FALSE, keep.frequencies = fitted, param = TRUE, eps = 1/10, iter = 40, print = FALSE, ...)

Arguments
formula
A linear model formula specifying the log-linear model. See loglm for its interpretation.
data
Numeric array or data frame. In the first case it specifies the array of frequencies; in then second it provides the data frame from which the variables occurring in the formula are preferentially obtained in the usual way.

This argument

start, param, eps, iter, print
Arguments passed to loglin.
fitted
logical: should the fitted values be returned?
keep.frequencies
If TRUE specifies that the (possibly constructed) array of frequencies is to be retained as part of the fitted model object. The default action is to use the same value as that used for fitted.
...
arguments passed to the default method.
Value

  • An object of class "loglm".
