coef extracts fitted model coefficients from splm()
or spautor()
fitted model objects. coefficients
is an alias for it.
Usage
# S3 method for spmod
coef(object, type = "fixed", ...)
# S3 method for spmod
coefficients(object, type = "fixed", ...)
Arguments
- object
- type
"fixed"
for fixed effect coefficients,"spcov"
for spatial covariance parameter coefficients, or"randcov"
for random effect variance coefficients. Defaults to"fixed"
. Iftype = "spcov"
, the coefficient vector is anspcov_params()
object (which means that has class matching the spatial covariance function used).- ...
Other arguments. Not used (needed for generic consistency).
Examples
spmod <- splm(z ~ water + tarp,
data = caribou,
spcov_type = "exponential", xcoord = x, ycoord = y
)
