[Gretl-users] wooldridge data

Hi all, I just noticed that for the 2nd edition of Wooldridge's Introductory Econometrics there's a gretlfiles.zip archive freely available online at http://www.thomsonedu.com/aise/economics/wooldridge_2e_datasets/ AFAIK however, these are not included directly with gretl, nor are they on the database server. Any reason for this? License issues? And for the current 3rd ed there are "only" ascii files, but also free downloads (http://www.thomsonedu.com/aise/economics/wooldridge3e_AISEdatasets/) I'm thinking of converting them into native gretl files (maybe let students do it as an exercise ;-). Again, are there any issues with posting them online, or even including them with gretl? I mean they didn't cook up the data, so it seems like public domain to me, but IANAL (no lawyer). cheers, sven
