Penalised regression with multiple sets of prior effects

Improves the predictive performance of ridge and lasso regression exploiting one or more sources of prior information on the importance and direction of effects ("transfer learning").

Installation

Install the current release from CRAN:

install.packages("transreg")

or the latest development version from GitHub or GitLab:

#install.packages("remotes")
remotes::install_github("lcsb-bds/transreg") # upstream

Reproducibility

The code for reproducing the simulations and applications shown in the manuscript is available in a vignette (https://lcsb-bds.github.io/transreg/articles/analysis.html). After installing the package with remotes::install_github("lcsb-bds/transreg",build_vignettes=TRUE) and restarting R, the vignette can also be loaded with vignette(topic="analysis",package="transreg").

Disclaimer

The R package transreg implements penalised regression with multiple sources of prior effects (Rauschenberger et al., 2023).
