ICS (version 1.4-1)

Tools for Exploring Multivariate Data via ICS/ICA

Description

Implementation of Tyler, Critchley, Duembgen and Oja's (JRSS B, 2009, ) and Oja, Sirkia and Eriksson's (AJS, 2006, ) method of two different scatter matrices to obtain an invariant coordinate system or independent components, depending on the underlying assumptions.
