This tutorial paper focuses on the complex-curve fitting technique, originally conceived for an application distinct from modal analysis. It aims at guiding other researchers

SciPy Curve Fitting: A Beginner’s Guide

Curve Fitting

First, curve fitting is an optimization problem. Each time the goal is to find a curve that properly matches the data set. There are two ways of improperly doing it – underfitting and overfitting. Underfitting is easier to grasp

Tutorial on Curve Fitting for GIS Wm Randolph Franklin Rensselær Polytechnic Institute Troy, NY, 12180 USA Phone: +1 (518) 276-6077, Fax: +1 (518) 276-6261 Internet: Abstract This paper is

Curve fitting is the process of specifying the model that provides the best fit to the curve in your data. Learn how using linear and nonlinear regression.

Unfortunately, most tutorials online don’t delve much deeper than providing examples of frequently used functions. There’s little content about how to think about curve
