This example illustrates some properties of splines. Splines are curves, which are usually required to be continuous and smooth. Splines are usually defined as piecewise polynomials of degree n with ...

In this paper D-optimal designs for free knot least squares spline estimation are investigated. In contrast to most of the literature on optimal design for spline regression models it is assumed that ...

The missing portions of variables subjected to SPLINE or MSPLINE transformations are handled the same way as for OPSCORE, MONOTONE, UNTIE, and LINEAR transformations (see the previous section). The ...

In this article a new methodology for estimating the term structure of interest rates is developed. Using polynomial splines, a reliable approximation to term structure may depend crucially upon ...

B-Spline curve fitting stands as a cornerstone in the realm of computational geometry, providing a flexible and robust approach to approximating intricate shapes and surfaces. This method relies on ...
