EstDepMoebius {MixedIndTests}

Dependence measures and statistics for test of independence between random variables

Description

This function computes copula-based dependence measures for Moebius versions of Spearmans's rho, van der Waerden's coefficient, and Savage's coefficient, as well as their combination for tests of independence between random variables.

Usage

EstDepMoebius(x, trunc.level = 2, graph = FALSE)

Arguments

x

Data matrix

trunc.level

Only subsets of cardinality <= trunc.level (default=2) are considered for the Moebius statistics.

graph

Set to TRUE if one wants the dependogram of P-values for the Moebius statistics

Value

stat

List of statistics (spearman, vdw, savage) and test combinations Ln and Ln2 (only pairs)

pvalue

P-values for the tests

cardA

Cardinaly of the subsets for the Moebius statistics

subsets

Subsets for the Moebius statistics
