summary method for objects of class
# S3 method for rlm summary(object, method = c("XtX", "XtWX"), correlation = FALSE, …)
the fitted model.
This is assumed to be the result of some fit that produces
an object inheriting from the class
rlm, in the sense that the components returned by the
rlmfunction will be available.
- Should the weighted (by the IWLS weights) or unweighted cross-products matrix be used?
- logical. Should correlations be computed (and printed)?
- arguments passed to or from other methods.
This function is a method for the generic function
summary() for class
It can be invoked by calling
summary(x) for an
x of the appropriate class, or directly by
summary.rlm(x) regardless of the
class of the object.
If printing takes place, only a null value is returned.
Otherwise, a list is returned with the following components.
Printing always takes place if this function is invoked automatically
as a method for the
