Many EViews estimation objects provide built-in routines for examining the gradients and derivatives of your specifications. You can, for example, use these tools to examine the analytic derivatives of your nonlinear regression specification in numeric or graphical form, or you can save the gradients from your estimation routine for specification tests.

The gradient and derivative views may be accessed from most estimation objects by selecting View/Gradients and Derivatives or, in some cases, View/Gradients, and then selecting the appropriate view.

If you wish to save the numeric values of your gradients and derivatives, you will need to use the gradient and derivative procedures. These procs may be accessed from the main Proc menu.

Note that all views and procs are not available for every estimation object or every estimation technique.
