\end{split}  \end{equation}  Since we could not detect scaling factor differences between MS patients and healthy controls, we do not think an approximation of covariance is within the scope of this paper. We do think it is necessary if other researchers believe the independence assumption is strongly violated for the particular disease they are studying, and we have included this the  point that this assumption is valid for MS only,  in the discussion section.
