NLSF Wizard

The new Nonlinear Least Squares Fitting Wizard makes nonlinear curve fitting fast and easy. The wizard steps you through the fitting process, including data and model selection. Since the wizard automatically initializes the fitting parameters, the procedure is simple. Choose from user-defined or built-in curve fitting functions, specify a subset of your data, define peak number and location for peak functions, impose weighting, and report results graphically and numerically during or after fitting. Plot residuals, confidence and prediction bands. Save the fitting procedure as a toolbar button for single-click repeat analyses.
