Hello. I want to try to pass daily closes of stock market in gretl, in order to try find some betas or play with the functions. The problem is that I do now know how to pass them, so the program can see the data as day-by-day of each one unique stock-entity. To clarify, I notice that when I pass 300 stocks in the program, the program see them as one, and even if I use the options of importing a csv file, I can't make it see that I have 300 stocks X 5 days, and not 1 type of stock for...N periods. Has anyone tried it before? Thank you in advance. -- D.Mexis
