eclust

The eclust package implements the methods developped in the paper:

An analytic approach for interpretable predictive models in high dimensional data, in the presence of interactions with exposures. Bhatnagar, Yang, Khundrakpam, Evans, Blanchette, Bouchard, Greenwood (2017) DOI:10.1101/102475.

Breifly, eclust is a two-step procedure: 1a) a clustering stage where variables are clustered based on some measure of similarity, 1b) a dimension reduction stage where a summary measure is created for each of the clusters, and 2) a simultaneous variable selection and regression stage on the summarized cluster measures.

Installation

You can install the development version of eclust from GitHub with:

install.packages("pacman")
pacman::p_install_gh("sahirbhatnagar/eclust")

Vignette

See the online vignette for example usage of the functions.

Credit

This package is makes use of several existing packages including:

  • glmnet for lasso and elasticnet regression
  • earth for MARS models
  • WGCNA for topological overlap matrices
