The test of exponentiality based on the mean residual life function revisited
We revisit the family of goodness-of-fit tests for exponentiality based on the mean residual life time proposed by Baringhaus and Henze …

A new omnibus test of fit based on a characterization of the uniform distribution
In this paper, we revisit the classical goodness-of-fit problems for univariate distributions; we propose a new testing procedure based …

Asymptotic efficiency of some nonparametric tests for location on hyperspheres
In the present paper, we show that several classical nonparametric tests for multivariate location in the Euclidean case can be adapted …

Bootstrap bandwidth selection and confidence regions for double smoothed default probability estimation
For a fixed time, $t$, and a horizon time, $b$, the probability of default (PD) measures the probability that an obligor, that has paid …

Characterizations of non-normalized discrete probability distributions and their application in statistics
From the distributional characterizations that lie at the heart of Stein’s method we derive explicit formulae for the mass functions of …

Conditional independence and predictive copula
In this paper, we address the concept of conditional independence between two random variables $X$ and $Y$ given the entity $Θ$. We …
