The exact region determined by Kendall's tau, Spearman's footrule and Blomqvist's beta

Jacob Israel Orenday Lares, Marcus Rockel

We determine the exact region $Ω_{τ, ϕ, β} := {(τ (C), ϕ (C), β (C)) : C \in C}$ of possible joint values of Kendall's tau, Spearman's footrule and Blomqvist's beta over the class $…

The exact region between Chatterjee's $ξ$ and Blomqvist's $β$

Jacob Israel Orenday Lares, Marcus Rockel

We determine the exact region of Chatterjee's rank correlation $ξ$ and Blomqvist's $β$ , that is, the set of all pairs $(ξ (C), β (C))$ where $C$ ranges over all bivariate copulas. The…
