Dear R users,
there are new versions of the following packages on CRAN:
o lmtest 0.9-0
o strucchange 0.9-4
o ineq 0.2-1
Changes/fixes in "lmtest":
There have been several bug fixes and the interfaces to all functions
have been improved such that their use is much more flexible.
Furthermore we have added:
- p values for the Durbin-Watson test
- studentized version of the Breusch-Pagan test
- flexible specification of the alternative hypothesis of the RESET
test
- simulated p values for the Harrison-McCabe test
- data sets with examples
Changes/fixes in "strucchange":
Besides a few minor changes and improvements there is a new fixed
version of the function Fstats(), which provides also computation of F
statistics based on
heteroskedasticity-consistent covariance estimation.
Changes/fixes in "ineq":
The empirical and theoretical Lorenz curves have now their own classes
with
plot- and lines-method. A data set with examples has been added and a
few bugs were fixed.

>From the DESCRIPTION:
Package: strucchange
Version: 0.9-4
Date: 2001-12-01
Title: Testing for Structural Change
Author: Achim Zeileis, Friedrich Leisch, Bruce Hansen,
Kurt Hornik, Christian Kleiber, Andrea Peters
Maintainer: Achim Zeileis <zeileis at ci.tuwien.ac.at>
Description: Testing on structural change in linear regression
relationships. It features tests/methods from the
generalized
fluctuation test framework as well as from the F test (Chow
test)
framework. This includes methods to fit, plot and test
fluctuation
processes (e.g. CUSUM, MOSUM, recursive/moving estimates)
and
F statistics, respectively. Furthermore it is possible to
monitor
incoming data online.
Depends: R (>= 1.3.0)

Package: ineq
Version: 0.2-1
Date: 2001-11-29
Title: Measuring inequality, concentration and poverty
Author: Achim Zeileis <zeileis at ci.tuwien.ac.at>
Maintainer: Achim Zeileis <zeileis at ci.tuwien.ac.at>
Description: Inequality, concentration and poverty measures
Lorenz curves (empirical and theoretical)
