Methods used for presenting the results of estimating spatial SAR models.
Usage
## S3 method for class 'sarlm'
summary(object, correlation = FALSE, Nagelkerke = FALSE, Hausman=FALSE, adj.se=FALSE, ...)
## S3 method for class 'sarlm'
print(x, ...)
## S3 method for class 'summary.sarlm'
print(x, digits = max(5, .Options$digits - 3),
signif.stars = FALSE, ...)
Arguments
object
sarlm object from lagsarlm or errorsarlm
correlation
logical; if 'TRUE', the correlation matrix of the estimated parameters including sigma is returned and printed (default=FALSE)
Nagelkerke
if TRUE, the Nagelkerke pseudo R-squared is reported
Hausman
if TRUE, the results of the Hausman test for error models are reported
adj.se
if TRUE, adjust the coefficient standard errors for the number of fitted coefficients
x
sarlm object from lagsarlm or errorsarlm in
print.sarlm, summary object from summary.sarlm for
print.summary.sarlm
digits
the number of significant digits to use when printing
signif.stars
logical. If TRUE, "significance stars" are printed
for each coefficient.
...
further arguments passed to or from other methods
Value
The summary function summary.sarlm returns the sarlm
object augmented with a coefficient matrix with probability values
for coefficient asymptotic standard errors for type="error" and for
type="lag" or "mixed" when object$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.
