Examination of the relationship between disinfection byproduct (DBP) sampling data and adverse birth outcomes illustrates a basic problem in environmental epidemiology: how to produce an exposure ...

This example then specifies a smoothed spline interpolation method on the GRID statement. As shown by the following output, the resulting surface plot is smoother still. libname reflib ...

Periodic Hermite spline interpolants on an equidistant lattice are represented by the Bézier technique as well as by the B-spline method. Circulant matrices are used to derive new explicit formulas ...

The SPLINE method fits a cubic spline curve to the input values. A cubic spline is a segmented function consisting of third-degree (cubic) polynomial functions joined together so that the whole curve ...

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 ...

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 ...
