  In this work, we propose extropy measures based on density copula,
distributional copula, and survival copula, and explore their properties. We
study the effect of monotone transformations for the proposed measures and
obtain bounds. We establish connections between cumulative copula extropy and
three dependence measures: Spearman's rho, Kendall's tau, and Blest's measure
of rank correlation. Finally, we propose estimators for the cumulative copula
extropy and survival copula extropy with an illustration using real life
datasets.
