Characterizations of independence between order statistics and rank indicators
Roberto Vila, Frederico Almeida
We study the independence between an order statistic and its corresponding rank indicator for independent nonnegative random variables. A general characterization is established th…
Conditional copula representations and extremal bounds for multivariate statistical functionals
Roberto Vila, Cira E G Otiniano, Carolyne Brito +1
The paper introduces a conditional copula representation that separates marginal distributions from dependence structures for multivariate expectations, and derives extremal bounds…
Bias analysis of a linear order-statistic inequality index estimator: Unbiasedness under gamma populations
Roberto Vila, Helton Saulo
This paper studies a class of rank-based inequality measures built from linear combinations of expected order statistics. The proposed framework unifies several well-known indices,…
