We consider a method of estimating an unknown regression curve by regression on a combination of low-order polynomial terms and trigonometric terms. Estimation based on trigonometric functions alone ...

In the present paper we consider a number of non-parametric regression methods for smoothing curves. These comprise (i) series estimators (classical Fourier and polynomial), (ii) cubic smoothing ...

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 ...
