I've proposed that "nonparametric multiplicative regression" be merged into this article. Here's why.
A Google search on "nonparametric regression" generates 369,000 hits, including dozens of book titles.
A Google search on "nonparametric multiplicative regression" generates 63 hits, most of which seem to be related to this paper, which describes a software package (apparently used by ecologists) in language like this: "a Gaussian (hump-shaped) curve ..." Which is fine, I guess, if you're an ecologist or a zoologist.
Clearly, NPMR is a subset of NPR, and should be subsumed under the larger topic. DavidCBryant 20:13, 27 February 2007 (UTC)
