IndependenceLinearStatistic-class {coin} | 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, varonly = FALSE, \dots)

where `object` is an object of class `"IndependenceTestProblem"`, `varonly` is a logical indicating that slot `covariance` (see ‘Slots’) should only contain the diagonal elements of the covariance matrix.

### Slots

`linearstatistic`:

  Object of class `"numeric"`. The linear statistic.

`expectation`:

  Object of class `"numeric"`. The expectation of the linear statistic.

`covariance`:

  Object of class `"VarCovar"`. The covariance or variance of the linear statistic.

`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.
