# S4 method for QuadTypeIndependenceTestStatistic
ApproxNullDistribution(object, B = 10000, …)
# S4 method for ScalarIndependenceTestStatistic
ApproxNullDistribution(object, B = 10000, …)
# S4 method for QuadTypeIndependenceTestStatistic
ExactNullDistribution(object, algorithm = c("auto", "shift", "split-up"), …)
# S4 method for ScalarIndependenceTestStatistic

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.

Value

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

Details

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