##### Class `"IndependenceTestProblem"`

Objects of class `"IndependenceTestProblem"`

represent the transformed
and original data structures corresponding to an independence problem.

- Keywords
- classes

##### Objects from the Class

Objects can be created by calls of the form

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

where `object`

is an object of class
`"'>IndependenceProblem"`

, `xtrafo`

is the regression
function \(g(\mathbf{X})\) and `ytrafo`

is the influence function
\(h(\mathbf{Y})\).
