CRAN Task View: Empirical Finance

This CRAN Task View contains a list of packages useful for empirical work in Finance, grouped by topic.

Besides these packages, a very wide variety of functions suitable for empirical work in Finance is provided by both the basic R system (and its set of recommended core packages), and a number of other packages on the Comprehensive R Archive Network (CRAN). Consequently, several of the other CRAN Task Views may contain suitable packages, in particular the Econometrics, Optimization, Robust, and TimeSeries Task Views.

The ctv package supports these Task Views. Its functions install.views and update.views allow, respectively, installation or update of packages from a given Task View; the option coreOnly can restrict operations to packages labeled as core below.

Contributions are always welcome and encouraged, either via e-mail to the maintainer or by submitting an issue or pull request in the GitHub repository linked above. See the Contributing page in the CRAN Task Views repo for details.

Standard regression models

• A detailed overview of the available regression methodologies is provided by the Econometrics task view. This is complemented by the Robust task view, which focuses on more robust and resistant methods.
• Linear models such as ordinary least squares (OLS) can be estimated by lm() (from by the stats package contained in the basic R distribution). Maximum Likelihood (ML) estimation can be undertaken with the standard optim() function. Many other suitable methods are listed in the Optimization view. Non-linear least squares can be estimated with the nls() function, as well as with nlme() from the nlme package.
• For the linear model, a variety of regression diagnostic tests are provided by the car, lmtest, strucchange, urca, and sandwich packages. The Rcmdr package provide user interfaces that may be of interest as well.
