AFNI Message Board

Dear AFNI users-

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.

Sincerely, AFNI HQ

Philippe,

Besides the subjective graphical methods of looking at things like Q-Q plots, there are several tests for normality. A few that look at skewness and kurtosis are D'Agostino & Tietjen 1971; D'Agostino 1971; D'Agostino, 1972; D'Agostino & Pearson 1973; Mulholland 1977; and Lin & Mudholkar 1980. These papers all seem to be in Biometrika.

For fMRI model diagnostics, you may want to look at
Diagnosis and exploration of massively univariate neuroimaging models, NeuroImage, Volume 19, Issue 3, July 2003, Pages 1014-1032
Wen-Lin Luo and Thomas E. Nichols
