This paper is concerned with the problem of existence of monotone and/or convex splines, having degree $n$ and order of continuity $k$, which interpolate to a set of ...

A general setting is given for smooth interpolating splines depending on a parameter such that as this parameter approaches infinity the spline converges to the piecewise linear interpolant. The ...

The interpolation methods used by PROC EXPAND assume that there are no restrictions on the range of values that series can have. This assumption can sometimes cause problems if the series must be ...

We can see the difference between SVI and spline more clearly here. As expected, SVI curves show nice “smiles.” On the other hand, the spline follows the datapoints more closely but can go only as far ...
