The gini-index measure
Description
An auxiliary function for the qualityF parameter in the FS.greedy.heuristic.reduct.RST, FS.DAAR.heuristic.RST and FS.greedy.heuristic.superreduct.RST functions.
It is based on the gini index as a measure of information (Stoffel and Raileanu, 2000).
Usage
X.gini(decisionDistrib)
Arguments
decisionDistrib
an integer vector corresponding to a distribution of attribute values.
Value
a numeric value indicating the gini index of an attribute.
