Paul McNelis has posted on his site (https://sites.google.com/site/pdmcnelisfordham/home/data-and-programs) a number of Matlab programs running the examples of his textbook on Neural Networks ("NN in Finance: Gaining Predictive Edge in the Market"). If you do not have access to Matlab I guess using some ingenuity you could run these programs as external code from Gretl. good luck :-) Stefano -- _________________________________________________________________________ Stefano Fachin Professore Ordinario di Statistica Economica Dip. di Scienze Statistiche Università di Roma "La Sapienza" P.le A.
