FitCurvatureTable

As of Version 7.0, FitCurvatureTable has become a property of NonlinearModelFit.

FitCurvatureTable

is a possible value for the RegressionReport option for NonlinearRegress which represents a table of curvature diagnostics.

Details and Options

To use FitCurvatureTable, you first need to load the Regression Common Functions Package. You can do this by using Needs["NonlinearRegression`"], which will automatically load the Regression Common Functions Package, or you can load the package directly by using Needs["RegressionCommon`"].
FitCurvatureTable includes the maximum relative intrinsic curvature, the maximum relative parameter-effects curvature, and the relative curvature of the least-squares solution confidence region.
Diagnostics in the fit curvature table give information about the validity of other diagnostics.
If curvatures are high, diagnostics based on linear approximations may give poor results.
