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

### Description

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

### Objects from the Class

Objects can be created by calls of the form

 `1` ``` new("IndependenceTestProblem", object, xtrafo = trafo, ytrafo = trafo, \dots) ```

where `object` is an object of class `"IndependenceProblem"`, `xtrafo` is the regression function g(X) and `ytrafo` is the influence function h(Y).

### Slots

`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.

### Extends

Class `"IndependenceProblem"`, directly.

### Known Subclasses

Class `"IndependenceLinearStatistic"`, directly.
Class `"IndependenceTestStatistic"`, by class `"IndependenceLinearStatistic"`, distance 2.
Class `"MaxTypeIndependenceTestStatistic"`, by class `"IndependenceTestStatistic"`, distance 3.
Class `"QuadTypeIndependenceTestStatistic"`, by class `"IndependenceTestStatistic"`, distance 3.
Class `"ScalarIndependenceTestStatistic"`, by class `"IndependenceTestStatistic"`, distance 3.
