Copula-Based Regression with Mixed Covariates by Saeed Aldahmani, Othmane Kortbi, Mhamed Mesfioui

“…Assoc. 2013, 108, 676–688) we extended copula-based regression to accommodate both continuous and discrete covariates. Specifically, we explored the construction of copulas to estimate the conditional mean of the response variable given the covariates, elucidating the relationship between copula structures and marginal distributions. …”

The Meaning of Time and Covariant Superderivatives in Supermechanics by Gil Salgado, José A. Vallejo-Rodríguez

“…This supermanifold admits several different Lie supergroup structures, and we analyze from a group-theoretic point of view what is the meaning of the usual covariant superderivatives, relating them to a change in the underlying group law. …”

Covariant phase space formalism for fluctuating boundaries by H. Adami, M. Golshani, M. M. Sheikh-Jabbari, V. Taghiloo, M. H. Vahidinia

“…Abstract We reconsider formulating D dimensional gauge theories, with the focus on the case of gravity theories, in spacetimes with boundaries. We extend covariant phase space formalism to the cases in which boundaries are allowed to fluctuate. …”
