I'm impressed that you still remembered this thread 6 months after the fact.

Actually what happened was, I read a comment of yours mentioning a lab that you worked in, was curious which lab, so started scanning all your comments starting from the earliest to see if you said more about it, noticed this comment, remembered that I had read a paper about whether independence is justified, couldn't find that paper but found the book instead.

BTW, what lab are you working in? ;)
