In (5), isn't the coefficient 4 in front of the sum missing?

Er, yeah. Well caught :-) Terry 19:51, 26 February 2009 (UTC)
I am afraid now the coefficient 16 is missing! ;-)
Also, with the illiterates like myself in mind, could you drop several words of motivation for (3) and (6)? Thanks!
One more thing. The conclusion of Lemma 1 involves expectation, but there is nothing random in the assumptions! What does the lemma actually say?
Oops, OK, I put the 4 in the right place, and added a few more words of description. I guess the symbol [math]\displaystyle{ {\Bbb E} }[/math] is used both for averaging and for expectation; I tried to clarify that it was averaging that was meant here. Terry 19:22, 1 March 2009 (UTC)
