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

Hello,

Yes, they are equivalent. The censoring regressors, where each only includes one value of 1 at the time point to censor and the rest of values to zero, can perfectly model signal at that time point. For instance, if the value of the time series is X, the weight of the corresponding censoring regressor will also be X so that the fit is perfect (i.e. no residual). In addition, "killing" time points will reduce the number of degrees of freedom in the very same number as adding an equivalent number of censoring regressors.

Hope this helps,
Cesar
