CURVE FITTING WITH PIECEWISE LINEAR FUNCTIONS

Abstract

A lot of suitable data is modeled by functions in the form of pieces of lines called piecewise-linear linear functions. This refinement function is related to hyperbole which has linear pieces as a form of approximation which is specifically useful for responding to asymptotic curves. The advantage of this function is that it has inheritance properties that continue at each order and are easy to analyze. The general form of this function is the sum of algebraic terms that are simpler but can represent more complex problem models.Keywords : curve fitting, linear function.
