If you are already an user, you are urged to switch to the new version. If you never tried it, you will be surprised by the amount of econometrics which can be done from the command line. Check the new project page.

The project The growth of firms and countries: distributional properties and economic determinants has been financed by the Italian Ministry of University and Research. The project is a joint effort of three units. I'm in charge of coordinating the project and, in particular, the research team at the Scuola Sant'Anna. Prof. Davide Fiaschi coordinates the University of Pisa unit and Prof. Enrico Scalas is responsible of the unit at the University of Piemonte Orientale.
