Provides basic quantities which are used in forming a wide variety of diagnostics for checking the quality of fitted model objects.
Arguments
- model
A fitted model object from
splm(),spautor(),spglm(), orspgautor().- ...
Other arguments. Not used (needed for generic consistency).
Value
A tibble with residuals (.resid), leverage values (.hat),
cook's distance (.cooksd), and standardized residuals (.std.resid).
Details
This function calls residuals.spmodel(), hatvalues.spmodel(),
and cooks.distance.spmodel() and puts the results into a tibble. It is
primarily used when calling augment.spmodel().
Examples
spmod <- splm(z ~ water + tarp,
data = caribou,
spcov_type = "exponential", xcoord = x, ycoord = y
)
influence(spmod)
