Non-parametric stats and cluster size correction
Hello everyone,

I have a question about the non-parametric statistics: I understand these are not exactly permutations, so does it correct for multiple comparisons? In my understanding it does, but since there are some cluster-size corrections designed for the non-parametric statistics I am wondering if not correcting the p-value can be a correct approach as it is for permutations.
On my data, if I use parametric statistics and an FDR correction for the cluster size, I have a similar result as if I use non-parametric statistics and not correct the p-value (with clusters a bit bigger and sometimes observed on both hemisphere when it is not with parametric statistics).

Hope that its clear.
Thanks in advance for any response,

Lena
