fanova for spd rejects the null all the time #2

Hi,

Your package is great, thanks for your hard work.

I am experiencing an issue when I use Frechet analysis of variance for data consisting of SPD matrices. The issue is that for samples that I can verify independently to have very similar Frechet means, I get p-values << 0.05 much more often than the nominal rate.

I was wondering if you have ever notice similar behavior. I'm happy to share my code if needed, though this is more of a general question.

Thanks,

NEV
