Greetings everybody: The supplementary material for our forthcoming paper titled "GRETL 1.6.0 and Its Numerical Accuracy" is made available in the Journal of Applied Econometrics Data Archive at the following url: http://econ.queensu.ca/jae/forthcoming/yalta-yalta/gretl1.6.0-review-sup.pdf This supplement explains the testing procedure of gretl in terms of numerical accuracy and also provides several tables that compare gretl's performance with the published results of various commercial econometric programs. It is expected to be published next year. Cheers, Talha -- A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. - Herm Allbright (1876-1944) --
