WebA weight of zero results in the basic thin plate Spline interpolation. Using a larger value of weight reduces the stiffness of the plate, and in the limit as phi approaches infinity, the surface approximates the shape of a membrane or rubber sheets, passing through the points. The interpolated surface is smooth. WebDescription. Fits a thin plate spline surface to irregularly spaced data. The smoothing parameter is chosen by generalized cross-validation. The assumed model is additive Y = f (X) +e where f (X) is a d dimensional surface. This is the classic nonparametric curve/surface estimate pioneered in statistics by Grace Wahba.
