===[[PCA applied to yield curves]]===
Prodded by [[User:Avraham]] as having no content or context, deprodded by [[User:Blotwell]], adding a reference to what it's supposed to be about, but still no content (disregarding the figures, which should be in [[Yield curve]], if anywhere) or context. Not expandable. — [[User:Arthur Rubin|Arthur Rubin]] | [[User_talk:Arthur_Rubin|(talk)]] 16:48, 24 June 2006 (UTC)

*'''Delete''' as nonsense vio of [[WP:NOR]]. Actually, this vapid stub is a fitting :-/ parody of PCA, a widely used but suspect method in statistics (the geometry is fine; the problem is with the ''interpretation''; as typically used, PCA is just a method for lying with statistics--- in a way, it's rather fascinating that such a thing is possible, but plainly I digress.) ---[[User:Hillman|CH]] 10:06, 26 June 2006 (UTC)
*People, people: you and I may be trained as mathematicians: we know what "rotation" and "curvature" are "supposed to mean", and we beat anyone with a big stick who is so ''sloppy'' as to use it to mean anything else, but it seems clear enough to me from the context that by rotation is meant "vertical shear" (which certainly does take functions to functions) and by "curvature" is meant some quadratic term. [http://www.americanbanker.com/glossary.html?alpha=P Here] is just one of the many Google hits for ''PCA "yield curve"'': note that it implies that yield curves are ''the'' important application of PCA in finance. '''Keep'''. —[[User:Blotwell|Blotwell]] 10:36, 27 June 2006 (UTC)
:No, I said rotation and I meant rotation; I just didn't take the time to try explain in detail. Keep googling, if you are curious, and you'll find my critique of PCA from several years ago. ---[[User:Hillman|CH]] 02:45, 28 June 2006 (UTC)
**'''Comment'''. Even [[User:Blotwell|Blotwell]]'s comment is correct, there's nothing '''correct''' in the article at present. Delete, and start over. — [[User:Arthur Rubin|Arthur Rubin]] | [[User_talk:Arthur_Rubin|(talk)]] 20:56, 27 June 2006 (UTC)
