CRAN Task View: Computational Econometrics
|Contact:||Achim.Zeileis at R-project.org|
Base R ships with a lot of functionality useful for computational
econometrics, in particular in the stats package. This
functionality is complemented by many packages on CRAN, a brief overview
is given below. There is also a considerable overlap between the tools
for econometrics in this view and for finance in the
is a suitable mailing list for obtaining help
and discussing questions about both computational finance and econometrics.
Finally, there is also some overlap with the
also covers a broad variety of tools for social sciences, e.g., including political science.
The packages in this view can be roughly structured into the following topics.
If you think that some package is missing from the list, please let me know.
Linear regression models
Linear models can be fitted (via OLS) with

methods such as

values of regressors in these models can be obtained and visualized using
Marginal effects tables for certain GLMs can be obtained using the
package. Interactive visualizations of both effects and marginal
effects are possible in
