## 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 '@'.
