## Citing earth

Please cite earth as follows:

S. Milborrow. Derived from mda:mars by T. Hastie and R. Tibshirani.
*earth: Multivariate Adaptive Regression Splines*, 2011. R package.

The following BibTex entry seems to do the trick.
The extra curly braces in the author field are necessary to get BibTex
to order the entry correctly on the last name of the first author.
The `url` field is optional.
@Manual{earthpackage,
title = {earth: Multivariate Adaptive Regression Splines},
author = {S. {Milborrow. Derived from mda:mars by T. Hastie and R. Tibshirani.}},
year = {2011},
note = {R package},
url = {http://CRAN.R-project.org/package=earth}
}

From within R you can use the following (but you will have to massage the results
to get BibTex to order the entry correctly):

> library(earth)
> citation("earth")
