R: Class ICS2

ics2-class {ICS} | R Documentation

## Class ICS2

### Description

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

### Objects from the Class

Objects can be created by calls of the form `new("ics2", ...)`. But usually objects are created by the function `ics2`. The Class inherits from the `ics` class.

### Slots

`gSkew`:

  Object of class `"numeric"`. Gives the generalized skewness measures of the components

`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.

`T1`:

  Object of class `"numeric"`. The first location vector.

`T2`:

  Object of class `"numeric"`. The second location vector.

`S1name`:

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

`S2name`:

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

`S1args`:

  Object of class `"list"`. Additional arguments needed when calling function S1.

`S2args`:

  Object of class `"list"`. Additional arguments needed when calling function S2.

`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.ics2`, `summary.ics2` But naturally the other methods like plot, coef, fitted and so from class ics work via inheritance.

### Note

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