⚠️There's a newer version (1.1.1) of this package.Take me there.

tilting (version 1.1)

Variable Selection via Tilted Correlation Screening Algorithm

Description

Implements an algorithm for variable selection in high-dimensional linear regression using the "tilted correlation", a new way of measuring the contribution of each variable to the response which takes into account high correlations among the variables in a data-driven way.
