*R package for MontgomeryNyhan BMA functions*
*********************************************

We have developed an R package implementing the functions described in our paper
"Bayesian Model Averaging: Theoretical Developments and Practical Applications"
(Political Analysis 18: 245-270) and incorporated in our replication materials
zip file
(http://www-personal.umich.edu/~bnyhan/montgomery-nyhan-replication.zip).


This package works on R 2.10 (it may work on versions 2.6-2.9 as well but does not work on 2.11) and requires that the BMA and BAS packages be installed (these are available on CRAN at http://cran.r-project.org). It does not work correctly
with factor variables - please create dummies rather than using as.factor().

There are three versions of the MontgomeryNyhan package:

Mac/Unix: http://www.duke.edu/~jmm61/MontgomeryNyhan_0.1.tar.gz
Windows-32: http://www.duke.edu/~jmm61/MontgomeryNyhan_0.1.zip
Windows-64: http://www.duke.edu/~jmm61/MontgomeryNyhan_0.11.zip

To install, download and decompress the appropriate file for your operating
system, then install it by selecting the installation option for local files
(local zip file for Windows or local package directory for Mac).

Information on the package appears below:

Description:

Package:       MontgomeryNyhan
Type:          Package

Author:        Jacob Montgomery and Brendan Nyhan
Maintainer:    Jacob Montgomery <jmm61@duke.edu>
Depends:       R (>= 2.6), stats, BMA, BAS, compare

SUGGESTS:      MASS
Description:   R functions from the article: Montgomery, Jacob M. and
               Brendan Nyhan. 2010. "Bayesian Model Averaging: Theoretical
               Developments and Practical Applicationss." Political
               Analysis 18(2): 245-270. The package slightly alters
               standard functions provided in the BMA and BAS packages.  In
               the future, we hope to incorporate the functionality we
               provide directly into the BAS package in collaboration with
               Merlise Clyde at Duke University.
