Multivariate two-sample permutation test with directional alternative for categorical data

Bonnini, Stefano; Borghesi, Michela - 2025

This paper presents a distribution-free test, based on the permutation approach, on treatment effects with a multivariate categorical response variable. The motivating example is a typical case-control biomedical study, performed to investigate the effect of the treatment called "assisted motor...

Copula Asymmetry Index (CAI++) : measuring asymmetric equity-volatility tail dependence for defensive allocation

Hatzopoulos, Peter; Statiou, Anastasios D. - 2026

This paper introduces the Copula Asymmetry Index (CAI), a rolling, rank-based measure of asymmetric tail dependence between equity returns and implied-volatility proxies. CAI is defined as the difference between the empirical frequency of joint "equity-down & volatility-up" tail events and that...
