coef
Extract Model Coefficients
coef
is a generic function which extracts model coefficients
from objects returned by modeling functions. coefficients
is
an alias for it.
- Keywords
- models, regression
Usage
coef(object, ...)
coefficients(object, ...)
Arguments
- object
- an object for which the extraction of model coefficients is meaningful.
- ...
- other arguments.
Details
All object classes which are returned by model fitting functions
should provide a coef
method or use the default one.
(Note that the method is for coef
and not coefficients
.)
Class "aov"
has a coef
method that does not report
aliased coefficients (see alias
).
Value
-
Coefficients extracted from the model object
object
.For standard model fitting classes this will be a named numeric vector.
