The FundAttribution site
has been up since June 2015. The website is in beta test.
Backtesting results are posted in the password-protected portion of the site. Historically, the predictions have been accurate: managers who have been skillful in the past tend to remain skillful. The statistical confidence in the predictions is high.
Forward-looking predictions for the large blend category are also posted on the site.
Registration for demo (free for MFO readers) is required to access the studies. Demo users can also see results for individual funds in two categories with limited functionality
