Hi Anderson
All my analyses are voxelwise. So I will do this variance test voxelwise as well.
Are you saying that I can just eyeballing the variance map and make a judgement?
I thought it's more objective if we can get a p value from Levene's test................
(but with such a extreme number of degree of freedom....it's likely that I will always get very small p value?)
Thanks so much.
Best Regards
Jie-Yu
