[Mne_analysis] Comparing conditions

[Daniel Goldenholz]

Hi Alex

For what it is worth, I thought about these kinds of questions some time ago
and presented a talk that was supposed to open up further discussion and
debate. The PDF of that talk is here:

http://www.nmr.mgh.harvard.edu/~daniel/links/presentation/stats_on_roi.pdf

It includes some basics on the mathematics and assumptions inherent in them.
Then the talk veers into the speculative with some thoughts on newer
possible methods for comparing conditions when you have multiple subjects
and multiple conditions.

I am still interested in developing these questions further, so let me know
if these ideas are helpful.

Daniel
