Least-Squares Method: Linear Regression for Curve Fitting
This tutorial explains curve fitting by linear approximation with derivation and coding. The least-squares approximation is the basis of linear and nonlinear curve fitting methods. #curvefitting is a common technique in experimental science and engineering. In this video #tutorial, #python is used as a programming language alongside NumPY and Matplotlib modules.
