Dear useRs,

the strucchange package for testing for structural change
has been updated: the current version is 1.2-4.
The most significant additions were two functions gefp()
and efpFunctional().

gefp() implements a class of generalized M-fluctuation
tests for testing for parameter instability or structural
change in general parametric models including generalized
linear models (GLMs). 

efpFunctional() provides infrastructure for inference based
on functionals applied to empirical fluctuation processes
such as automatic tabulation of critical values and a choice
of a suitable visualization method.

The theory behind both functions is described in Zeileis
& Hornik (2003), the implementation ideas are explained in
Zeileis (2004). Links to both papers are available from
my web page: http://www.ci.tuwien.ac.at/~zeileis/

Best wishes,

Title: Testing for Structural Change
Author: Achim Zeileis, Friedrich Leisch, Bruce Hansen,

Description: Testing, dating and monitoring of structural change in
             linear regression relationships.
             strucchange 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.
             It is possible to monitor incoming data online using
             fluctuation processes.
             Finally, the breakpoints in regression models with
             structural changes can be estimated together with
             confidence intervals. Emphasis is always given to methods
             for visualizing the data.
