"WebJan 20, 2024 · Thin-plate splines have the edge in terms of MSE over the cubic regression spline, but are much more costly to set up the basis function for. I'd be interested to see whether the effects of the two splines are really that different given the uncertainty in their estimation at end points of a variable, esp if the data is patchy. – Gavin Simpson " - Python thin plate spline

WebThe original thin plate (formerly Laplacian) smoothing spline surface fitting technique was described by Wahba (1979), with modifications for larger data sets due to Bates and Wahba (1982), Elden (1984), Hutchinson (1984) and Hutchinson and de Hoog (1985).
