Curve Fitting Tool

With the Curve Fitting Tool, you can visually explore data and fits as scatter plots, graphically evaluate the goodness of fit using residuals and prediction bounds, and access graphical user interfaces (GUIs) for importing and fitting data, and for plotting and analyzing fits to the data.

By clicking the Data, Fitting, Exclude, Plotting, or Analysis buttons, you can launch the associated GUIs, which are described below.

• Data GUI
• Import, preview, name, and delete data sets.
• Smooth noisy data.
• Fitting GUI
• Fit data using a library or custom equation, a smoothing spline, or an interpolant.
• Examine and compare the fit results including fitted coefficient values and goodness of fit statistics.
• Keep track of all the fits and associated data sets for the current session.
• Exclude GUI
• Mark data to be excluded from a fit.
• View the exclusion rule.
• Plotting GUI
• Control which data sets and fits are displayed in the Curve Fitting Tool.
• Analysis GUI
• Evaluate (interpolate or extrapolate), differentiate, or integrate a fit.
• Plot the analysis results and the data set.
