R Documentation
Class "IndependenceTestStatistic" and its subclasses
Description
Objects of class "IndependenceTestStatistic" and its subclasses
"MaxTypeIndependenceTestStatistic",
"QuadTypeIndependenceTestStatistic" and
"ScalarIndependenceTestStatistic" represent the test statistic, the
linear statistic, and the transformed and original data structures
corresponding to an independence problem.
Objects from the Class
Class "IndependenceTestStatistic" is a virtual class, so objects
cannot be created from it directly.
where object is an object of class
"IndependenceLinearStatistic", alternative is a character
specifying the direction of the alternative hypothesis and paired is a
logical indicating that paired data have been transformed in such a way that
the (unstandardized) linear statistic is the sum of the absolute values of the
positive differences between the paired observations.
