CRAN Task View: 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 those in the task views on
is a suitable mailing list for obtaining help
and discussing questions about both computational finance and econometrics.
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 contact the maintainer.
