fitted(object, type = "response", ...)
## S3 method for class 'spautor'
fitted.values(object, type = "response", ...)
## S3 method for class 'spglm'
fitted(object, type = "response", ...)
## S3 method for class 'spglm'
fitted.values(object, type = "response", ...)
## S3 method for class 'spgautor'
fitted(object, type = "response", ...)

Details
When type
is "response"
, the fitted values
for each observation are the standard fitted values X \hat{\beta}
.
When type
is "spcov"
the fitted values for each observation
are (generally) the best linear unbiased predictors of the spatial dependent and spatial
independent random error. When type
is "randcov"
, the fitted
values for each level of each random effect are (generally) the best linear unbiased
predictors of the corresponding random effect. The fitted values for type
"spcov"
and "randcov"
can generally be used to check assumptions
for each component of the fitted model object (e.g., check a Gaussian assumption).
Value
The fitted values according to type
.
Examples
spmod <- splm(z ~ water + tarp,
data = caribou,
spcov_type = "exponential", xcoord = x, ycoord = y
)
fitted(spmod)
fitted.values(spmod)
fitted(spmod, type = "spcov")
