GRridge-package: Implements adaptive group-regularized (logistic) ridge...

Description Details Author(s) References See Also


This package implements adaptive group-regularized (logistic) ridge regression by use of co-data. It uses co-data to improve predictions of binary and continuous response from high-dimension (e.g. genomics) data. Here, co-data is auxiliary information on variables (e.g. genes), such as annotation or p-values from other studies. The package includes convenience functions to convert such co-data to the correct input format. In additiion, in includes functions for evaluating the predictive performance.
