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

Hi Gang,

Thank you for suggesting this analysis.
I ran it, but I am still puzzled about some aspects:

1) The terms "(Oxytocin|subject)" and "(Pleasantness|subject)" that you suggest are to be interpreted as random slope of oxytocin (and pleasantness) across subjects with correlated intercept? How does that change the regression equation?

2) I have a significant interaction effect between Oxytocin and Pleasantness? How do I interpret and visualise that?

3) Same thing for the 4way interaction "Session*Velocity*Pleasantness*Oxytocin".

Generally speaking, how can I simulate the statistics of this model in excel starting from the beta values of the 2x2 conditions (Sessions X Velocity) and respective quantitative variables (Oxytocin and Pleasantness)?
