In mathematics, a spline is a special function defined piecewise by polynomials. In interpolating problems, spline interpolation is often preferred to polynomial interpolation because it yields similar results, even when using low degree polynomials, while avoiding Runge's phenomenon for higher degrees.

Webvariety of work on splines in statistics. Splines are pre- sented as a nonparametric function estimating technique. After a general introduction to the theory of interpolating and smoothing splines, splines are treated in the nonpar- ametric regression setting. The method of cross-valida- tion for choosing the smoothing parameter is discussed WebFor a univariate sample x, x, a D D -degree polynomial expansion is given by. x ↦ (1,x,x2,⋯,xD). x ↦ ( 1, x, x 2, ⋯, x D). To motivate regression splines, consider the data below (black dots), along with the fit of a cubic polynomial globally to the data (blue line). It’s clear that a single cubic polynomial to the entire dataset is ... Basis splines are just a type of spline formation. Splines can look different depending on which type you use. This makes sense — there are many different ways to form a line through data points. Take this image for example: Each colored line is a different type of spline.
