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

is a possible value for the RegressionReport option for NonlinearRegress which represents the estimated bias in the parameter estimates.


  • To use , you first need to load the Regression Common Functions Package. You can do this by using , which will automatically load the Regression Common Functions Package, or you can load the package directly by using .
  • gives a vector of the estimated differences between the parameter estimates and the true parameter values.
  • is based on the average curvature of the solution locus tangential to the leastsquares estimate.
