Use the "Fit Model" platform. Add column Y to "Y" and columns X and Z to "Model Effects". To add powers of independent variables choose "Polynomial to Degree" under the "Macros" roll list. When you're done just hit "Run Model".

Is there a way to determine the resulting formula? Will this same setup work for surface fitting?

Under the top red triangle, under Save Columns, you can select Prediction Formula option.
