Return Value
A double array containing the inverse of the Hessian times the gradient vector, computed at the initial estimates.Remarks
Note that the HessianOption property must be set to true and the SetInitialEstimates method must be invoked prior to invoking this method. Otherwise, the method throws an InvalidOperationException exception.
