RE: NBS: test_stat interpretation with FDR analysis
Hi Cecile,

It is not possible to get a negative F statistic.

If you feel comfortable doing so, I suggest that you send me your data, design matrix and contrasts. I can then try to replicate the error locally.

Hi Andrew,

After, few days of running the FDR analysis with the model you advised me to use, I am finding the same kind of results than before.
More annoyingly, I am also getting negative value of f-test when I am looking at the significant links.

I really do not get it! I checked my subject matrix, they are sparse and with nothing special (no NaN or Inf).
Any idea/ suggestion?

Thanks a lot for your patience.
Cecile
