Diagonal sections of copulas, multivariate conditional hazard rates and distributions of order statistics for minimally stable lifetimes

open access: yesDependence Modeling, 2021
As a motivating problem, we aim to study some special aspects of the marginal distributions of the order statistics for exchangeable and (more generally) for minimally stable non-negative random variables T1, ..., Tr. In any case, we assume that T1, ...,

On the use of L-functionals in regression models

open access: yesOpen Mathematics, 2023
In this article, we survey and unify a large class or LL-functionals of the conditional distribution of the response variable in regression models.

Sequential change-point detection in a multinomial logistic regression model

open access: yesOpen Mathematics, 2020
Change-point detection in categorical time series has recently gained attention as statistical models incorporating change-points are common in practice, especially in the area of biomedicine.

Multivariate radial symmetry of copula functions: finite sample comparison in the i.i.d case

open access: yesDependence Modeling, 2021
Given a d-dimensional random vector X = (X1, . . ., Xd), if the standard uniform vector U obtained by the component-wise probability integral transform (PIT) of X has the same distribution of its point reflection through the center of the unit hypercube,

Asymptotic normality of the relative error regression function estimator for censored and time series data

open access: yesDependence Modeling, 2021
Consider a survival time study, where a sequence of possibly censored failure times is observed with d-dimensional covariate The main goal of this article is to establish the asymptotic normality of the kernel estimator of the relative error regression ...

Dispersive order comparisons on extreme order statistics from homogeneous dependent random vectors

open access: yesDependence Modeling, 2021
In this paper, we investigate sufficient conditions for preservation property of the dispersive order for the smallest and largest order statistics of homogeneous dependent random vectors.

Recent developments on the construction of bivariate distributions with fixed marginals

open access: yesJournal of Statistical Distributions and Applications, 2014
Constructing a bivariate distribution with specific marginals and correlation has been a challenging problem since 1930s. In this survey we shall focus on the recent developments on the FGM-related distributions, including Sarmanov and Lee’s ...

Sequences of expected record values [PDF]

open access: yesElectronic Journal of Probability, 2019
We investigate conditions in order to decide whether a given sequence of real numbers represents expected record values arising from an independent, identically distributed, sequence of random variables.

Bivariate Extension of Past Entropy

open access: yesJournal of the Iranian Statistical Society, 2020
. Di Crescenzo and Longobardi (2002) has been proposed a measure of uncertainty related to past life namely past entropy. The present paper addresses the question of extending this concept to bivariate set-up and study some properties of the proposed ...
