Curve Fitting Toolbox
Curve Fitting Toolbox lets you fit multiple candidate models to a data set. You can then evaluate goodness of fit using a combination of descriptive statistics, visual inspection, and validation.
Curve Fitting Toolbox provides a wide range of descriptive statistics, including:
The Table of Fits lists all of the candidate models in a sortable table, enabling you to quickly compare and contrast multiple models.
The toolbox enables you to visually inspect candidate models to reveal problems with fit that are not apparent in summary statistics. For example, you can:
Curve Fitting Toolbox supports validation techniques that help protect against overfitting. You can generate a predictive model using a training data set, apply your model to a validation data set, and then evaluate goodness of fit.
