Occasionally, I am also involved in software development.
I am a coauthor of the following R packages:
- A new project: package "countreg" aims at providing tools for count data regression. This is still under development, hence not yet available via CRAN. The package contains, among other things, the fitting functions for hurdle and zero-inflation models that have been available via the "pscl" package before. Current (installable!) versions are available from the R-Forge development server at R-Forge.R-project.org/projects/countreg/.
- "AER: Applied Econometrics with R" Functions, data sets, examples and vignettes for the book Applied Econometrics with R, Springer 2008 (with Achim Zeileis).
Available at CRAN.R-project.org/package=AER (first release: 2008-05-28).
- "strucchange: An R package for testing, dating and monitoring of structural change in linear regression relationships" (with Achim Zeileis, Friedrich Leisch, Kurt Hornik).
Available at CRAN.R-project.org/package=strucchange (first release: 2001-05-17).
