Dear R users,

An updated version of the np package has recently been uploaded to CRAN (version 0.20-0). Version 0.20-0 is documented in

Tristen Hayfield and Jeffrey S. Racine (2008). Nonparametric Econometrics: The np Package. Journal of Statistical Software 27(5). URL http://www.jstatsoft.org/v27/i05/

and also in a vignette (vignette("np",package="np")). There is also a FAQ located in the package browse directory (np_faq.pdf, also available at http://socserv.mcmaster.ca/racine/np_faq.pdf).

A much more thorough treatment of the subject matter can be found in Li, Q. and J. S. Racine (2007), Nonparametric Econometrics: Theory and Practice, Princeton University Press, ISBN: 0691121613 (768 Pages) for those who might be interested

Information on the np package:

This package provides a variety of nonparametric (and semiparametric) kernel methods that seamlessly handle a mix of continuous, unordered, and ordered factor datatypes. We would like to gratefully acknowledge support from the Natural Sciences and Engineering Research Council of Canada (NSERC:www.nserc.ca), the Social Sciences and Humanities Research Council of Canada (SSHRC:www.sshrc.ca), and the Shared Hierarchical Academic Research Computing Network (SHARCNET:www.sharcnet.ca).

Changes from 0.14-3 to 0.20-0

We are grateful to John Fox, Achim Zeilies, Roger Koenker, and numerous users for their valuable feedback which resulted in an improved version of the package.
