Computation of the Reference Distribution

Description

Methods for computation of the asymptotic, approximative (Monte Carlo) and exact reference distribution.

Usage

## S4 method for signature 'MaxTypeIndependenceTestStatistic'
AsymptNullDistribution(object, ...)
## S4 method for signature 'QuadTypeIndependenceTestStatistic'
AsymptNullDistribution(object, ...)
## S4 method for signature 'ScalarIndependenceTestStatistic'
AsymptNullDistribution(object, ...)

## S4 method for signature 'MaxTypeIndependenceTestStatistic'
ApproxNullDistribution(object, B = 10000, ...)
## S4 method for signature 'QuadTypeIndependenceTestStatistic'
ApproxNullDistribution(object, B = 10000, ...)
## S4 method for signature 'ScalarIndependenceTestStatistic'
ApproxNullDistribution(object, B = 10000, ...)

## S4 method for signature 'QuadTypeIndependenceTestStatistic'
ExactNullDistribution(object, algorithm = c("auto", "shift", "split-up"), ...)
## S4 method for signature 'ScalarIndependenceTestStatistic'
ExactNullDistribution(object, algorithm = c("auto", "shift", "split-up"), ...)

Arguments

object

an object from which the asymptotic, approximative (Monte Carlo) or exact reference distribution can be computed.

B

a positive integer, the number of Monte Carlo replicates used for the computation of the approximative reference distribution. Defaults to 10000.

algorithm

a character, the algorithm used for the computation of the exact reference distribution: either "auto" (default), "shift" or "split-up".

...

further arguments to be passed to or from methods.

Details

The methods AsymptNullDistribution, ApproxNullDistribution and ExactNullDistribution compute the asymptotic, approximative (Monte Carlo) and exact reference distribution respectively.

Value

An object of class "AsymptNullDistribution", "ApproxNullDistribution" or "ExactNullDistribution".
