summary.sarlm: summary method for class sarlm

Description

Methods used for presenting the results of estimating spatial SAR models.

Usage

summary.sarlm(object, ...)
print.sarlm(x, ...)
print.summary.sarlm(x, digits = max(5, .Options$digits - 3),
	signif.stars = FALSE, ...)

Arguments

object

sarlm object from lagsarlm or errorsarlm

x

sarlm object from lagsarlm or errorsarlm in print.sarlm, summary object from summary.sarlm for print.summary.sarlm

digits

the number of significant digits to use when printing

signif.stars

logical. If TRUE, "significance stars" are printed for each coefficient.

...

further arguments passed to or from other methods

Value

• The summary function summary.sarlm returns the sarlm object augmented with a coefficient matrix with probability values for coefficient asymptotic standard errors for type="error" and for type="lag" or "mixed" when object$ase=TRUE, or a coefficient matrix with probability values for likelihood ratio tests between the model as reported and models with independent variables dropped in turn.
