Sorry to ask a "simple and stupid" question on the list, but couldn't find an answer from any Manual or Command reference (nor Gretl-wiki search). Is there a simple way to perform out-of-sample forecast for a cross section data? In addition to my own work @ Orava RES, I'm a part-time lecturer at the Aalto University (formerly Helsinki University of Technology) and my intention is to use Gretl on "Quantitative Methods for Real Estate Economics" course: students will be required to do their course assignment using Gretl - and as an old E-Views user I'm just learning how to use Gretl myself.
