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:

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,

I am running Deconvolve on several subjects, and have run into multicollinearity problems with a few of them. In this design, stimuli were presented and the participant had the choice to take or pass on them; certain ones rendered only good or bad outcomes, while others produced both good and bad outcomes or a neutral (none) outcome. There were 7 runs with 149 scans after dropping the first 5, for a total of 1043 runs. The TR was 2s.

The stim_times were further split according to whether they corresponded to the display of the stimulus (dPass, dTake) - which were subdivided according to jitter - and the outcome of the stimulus. A TENT function was used in both cases, and was modeled with a larger time interval in the display conditions in order to accommodate for jitters of different lengths. Each stim_time was amplitude modulated with the magnitude and probability of the good and bad outcomes.

However, halfway through the Deconvolve output, I get the following collinearity error for several columns in one of the .1D files:

*+ WARNING: !! * Columns 418 [out_pass_good#7] and 432 [out_pass_good#21] are nearly collinear!

The content of that .1D file is only five rows, which is relatively short compared to the other .1D files:

400*100,66,60,33
1172*60,33,20,33
1578*60,83,20,83
1940*100,17,60,83
2018*60,33,20,66

I am unsure of what, exactly, is causing this collinearity problem. Is it a result of too many regressors splitting up all of the TRs, and if so, how can this be remedied without collapsing conditions? Would -GOFORIT be a viable option here, even with 9 warnings?


Thank you again for your time,

-Andrew
