mRMRe (version 2.1.2.1)

causality: Accessor function for the 'causality' information in a mRMRe.Filter and mRMRe.Network object.

Description

The causality data is compute using the co-information lattice algorithm on each V-structure (feature, target, feature). Given that this procedure is computed for each pair of features, the minimum result is kept. A negative score indicates putative causality of the feature to the target.

Usage

# S4 method for mRMRe.Filter
causality(object)
# S4 method for mRMRe.Network
causality(object)

Arguments

object

a mRMRe.Filter or mRMRe.Network object.
