Web11 Jun 2024 · The only spline inside fit where any form of approximation to your data arises is in the smoothing spline, and you have not asked about that one. But remember that ANYTHING that is explicitly called interpolation will always predict the data with essentially no error. An interpolant is only worried about what it will do BETWEEN the data points.
