Introduction. Curve Fitting Toolbox™ software uses the method of least squares when fitting data. Fitting requires a parametric model that relates the response data to the predictor data with one or more coefficients. The result of the fitting process is an estimate of the model coefficients. Introduction  Error Distributions  Linear Least Squares  Weighted Least Squares. Solve linear leastsquares problems with bounds or linear constraints; Nonlinear Least Squares (Curve Fitting) Solve nonlinear leastsquares (curvefitting). The linear least squares fitting technique is the simplest and most commonly applied form of linear regression and provides a solution to the problem of finding .
