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

> Does 3dMVM support within-subject covariates or is that still a 3dLME domain?

This is a very good question. Seriously!

3dMVM does not prevent one to run analysis with within-subject covariates. However, it is a delicate endeavor when dealing with within-subject covariates for the following two reasons:

1) How much does a within-subject covariate correlate with other variables, especially those within-subject factors? This involves a rarely discussed issue of centering.

2) Each subject may have a separate covariate effect.

Because of these complications, especially 2), 3dLME would be a better tool to handle within-subject covariates.
