Description Usage Arguments Value References Examples

Calculates several dependence measures derived from the copula density. All
measures except `"blomqvist"`

are computed by quasi Monte Carlo methods
(see `rkdecop()`

.

dep_measures(object, measures = "all", n_qmc = 10^3, seed = 5)
``` |

`object` |
an object of class |

`measures` |
which measures to compute, see |

`n_qmc` |
the number of quasi Monte Carlo samples. |

`seed` |
the seed for quasi Monte Carlo integration. |

A named vector of dependence measures.

The following measures are available:

`"kendall"`

Kendall's

*τ*, see Nelsen (2007); computed as the sample version of a quasi Monte Carlo sample.`"spearman"`

Spearman's

*ρ*, see Nelsen (2007); computed as the sample version of a quasi Monte Carlo sample.`"blomqvist"`

Blomqvist's

*β*, see Nelsen (2007); computed as*4C(0.5, 0.5) - 1*.`"gini"`

Gini's

*γ*, see Nelsen (2007); computed by quasi Monte Carlo integration.`"vd_waerden"`

van der Waerden's coefficient, see Genest and Verret (2005); computed as the sample version of a quasi Monte Carlo sample.

`"minfo"`

mutual information, see Joe (1989); computed by quasi Monte Carlo integration.

`"linfoot"`

Linfoot's correlation coefficient, see Joe (1989); computed by quasi Monte Carlo integration.
