Free R Packages

To lower the threshold to apply our new methods, the customer intelligence cluster of Ghent University develops free R packages for the free R language (see CRAN website).

Bayesian Quantile Regression: bayesQR

To download the bayesQR package: click here.

This R package implements bayesian quantile regression using the asymmetric Laplace distribution, both continuous as well as binary dependent variables are supported. The package consists of implementations of the methods of Yu & Moyeed (2001) and Benoit & Van den Poel (2011). Below you find the latter reference:

Ensemble Classifiers for Binary Classification: GAMens (includes GAMbag, GAMrsm and GAMens)

To download the GAMens package: click here.

This package implements the GAMbag, GAMrsm and GAMens ensemble classifiers for binary classification (De Bock et al., 2010). The ensembles implement Bagging (Breiman, 1996), the Random Subspace Method (Ho, 1998), or both, and use Hastie and Tibshirani's (1990) generalized additive models (GAMs) as base classifiers. Once an ensemble classifier has been trained, it can be used for predictions on new data. A function for cross validation is also included.
