We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:
https://discuss.afni.nimh.nih.gov
Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.
The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.
Thanks a lot for the detailed explanation. So the bottom line is basically the Std Dev of the betas computed. If one has fewer events, the SD will be larger. But above a certain number of events, the actual difference between the number of events per type is less crucial, as the beta estimates will be less noisy.
