Hello Statalisters. I have a do file that use a macro in order to run
several regression models, using different lags each time. What I'm
following pasting is the syntax corresponding to ISIN=8. I have eleven
different ISIN (let's call them IDs). How can I introduce the issue of
different values there. I think this a matter of nesting, but I never
have used that. Even the text file with the results is associated to
the number (ISIN) selected. My full list includes 8, 225, 29, 220, 18,
251, 222 ,221, 244, 24, 276

Thanks for your contribution
