# IndependenceLinearStatistic-class: Class '"IndependenceLinearStatistic"' In coin: Conditional Inference Procedures in a Permutation Test Framework

 IndependenceLinearStatistic-class R Documentation

## Class `"IndependenceLinearStatistic"`

### Description

Objects of class `"IndependenceLinearStatistic"` represent the linear statistic and the transformed and original data structures corresponding to an independence problem.

### Objects from the Class

Objects can be created by calls of the form

`     new("IndependenceLinearStatistic", object, ...)`

where `object` is an object of class `"IndependenceTestProblem"`.

### Slots

`linearstatistic`:

Object of class `"matrix"`. The linear statistic for each block.

`expectation`:

Object of class `"matrix"`. The expectation of the linear statistic for each block.

`covariance`:

Object of class `"matrix"`. The lower triangular elements of the covariance of the linear statistic for each block.

`xtrans`:

Object of class `"matrix"`. The transformed `x`.

`ytrans`:

Object of class `"matrix"`. The transformed `y`.

`xtrafo`:

Object of class `"function"`. The regression function for `x`.

`ytrafo`:

Object of class `"function"`. The influence function for `y`.

`x`:

Object of class `"data.frame"`. The variables `x`.

`y`:

Object of class `"data.frame"`. The variables `y`.

`block`:

Object of class `"factor"`. The block structure.

`weights`:

Object of class `"numeric"`. The case weights.
