OBSOLETE REGRESSION COMMON PACKAGE SYMBOL
AsymptoticCovarianceMatrix
As of Version 7.0, 
has become a property of NonlinearModelFit.
has become a property of NonlinearModelFit.
is a possible value for the RegressionReport option for NonlinearRegress which represents the estimated covariance matrix of the fit parameters.
Details
- 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 
. - The estimated covariance matrix is based on the linear approximation to the fitted nonlinear model.
- The asymptotic covariance matrix is equivalent to
where 
is the estimated variance and 
is the design matrix for the linear model approximation.
