residuals.fm {ftsa} | R Documentation |
After fitting a functional model, it is useful to inspect the residuals.
This function extracts the relevant information from the fit object and puts it in a form suitable for
plotting with image
, persp
, contour
, filled.contour
, etc.

Produces an object of class “fmres” containing the residuals from the model.
