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