What does "piling up" mean[edit]

Okay, I give up. Can someone PLEASE explain to me what the term "piling up" has to do with this lemma?--Will2k 18:13, 9 February 2006 (UTC)

LOL, yeah, I've never figured it out either. Matsui is Japanese, so maybe it's just a term that didn't translate well. — Matt Crypto 18:35, 9 February 2006 (UTC)

Well, adding several random variables ("piling them up"), what do we get? I just added a 2nd related definition of bias, which shows that "piling up" partial knowledge leads to multiplying the (2nd def) biases. E.g. One (2nd def) bias zero (P(1)=P(0)=1/2) renders everything equidistributed, while adding a (2nd def) bias P(1) or P(0)=1, does not change the overall bias up to sign DocMJV 22:57, 13 September 2007 (UTC)

Wow. I completely forgot about this stuff. Thanks for the explanation. Hopefully others will find this useful in the future. --Will2k 16:32, 1 October 2007 (UTC)
