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
loglmfor 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
TRUEspecifies 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 forfitted. - ...
- arguments passed to the default method.
Value
- An object of class
"loglm".
