Yes, there is a free basic version of our abnormal return calculator - it will calculate for you abnormal returns at the AR level without test statistics. Results will be made available as direct downloads on the graphical user interface - no emails with results will be sent.
Further, if you convince your university librarian to list us in the library's student service catalog, we will whitelist the whole student email domain of your university - at no cost for a limited set of universities. Get in contact with info@eventstudytools.com in case you want to claim this offer.
