Restricted Cubic Spline Regression: A Brief Introduction

Cubic splines tend to be poorly behaved at the two tails (before the first knot and after the last knot). To avoid this, restricted cubic splines are used. A r estricted cubic spline is a cubic spline in which the splines are constrained to be linear in the two tails. This generally provides a better fit to the data, and also has

Restricted Cubic Spline for Linearity Test & Continuous ...

• The spline curve was constructed by using a different cubic polynomial curve between each knots. The spline will bend around these knots. • In other words, a piecewise cubic curve is made of pieces of different cubic curves glued together. The pieces are so well matched where they are glued that the gluing is not obvious. Splines –

as the method of cubic splines. The spline interpolation kernel is not zero for nonzero integers. As a result, the ck’s must be determined by solving a matrix problem. In addition to being 0 or 1 at the interpolation nodes, the in- terpolation kernel must …

Solving a tridiagonal linear system

can be used to de ne an n n tridiagonal matrix associated with interpolation by cubic splines. The functions A=spline matrix(g) and [a,b,c]=spline sparse matrix(g) return dense and sparse versions of this matrix. In order to manufacture a problem, we choose a simple solution vector x and compute f = Ax. However,
