Class ICS

Description

A S4 class to store results from an invariant coordinate system transformation or independent component computation based on two scatter matrices.

Objects from the Class

Objects can be created by calls of the form new("ics", ...). But usually objects are created by the function ics.

Slots

gKurt:

Object of class "numeric". Gives the generalized kurtosis measures of the components

UnMix:

Object of class "matrix". The unmixing matrix.

S1:

Object of class "matrix". The first scatter matrix.

S2:

Object of class "matrix". The second scatter matrix.

S1name:

Object of class "character". Name of the first scatter matrix.

S2name:

Object of class "character". Name of the second scatter matrix.

Scores:

Object of class "data.frame". The underlying components in the invariant coordinate system.

DataNames:

Object of class "character". Names of the original variables.

StandardizeB:

Object of class "character". Names standardization method for UnMix.

StandardizegKurt:

Object of class "logical". States wether the generalized kurtosis is standardized or not.

Methods

For this class the following generic functions are available: print.ics, summary.ics, coef.ics, fitted.ics and plot.ics

Note

In case no extractor function for the slots exists, the component can be extracted the usual way using '@'.
