Consistency and asymptotic normality of the maximum likelihood estimator in a zero-inflated generalized Poisson regression [PDF]
Poisson regression models for count variables have been utilized in many applications. However, in many problems overdispersion and zero-inflation occur.

Nonoscillatory solutions of the four-dimensional difference system
We study asymptotic properties of nonoscillatory solutions for a four-dimensional system \[\begin{aligned} \Delta x_{n}&= C_{n}\, y_{n}^{\frac{1}{\gamma}} \\ \Delta y_{n}&= B_{n}\, z_{n}^{\frac{1}{\beta}} \\ \Delta z_{n}&= A_{n}\, w_{n}^{\frac{1}{\alpha}}

A New Class of Reduced-Bias Generalized Hill Estimators
The estimation of the extreme value index (EVI) is a crucial task in the field of statistics of extremes, as it provides valuable insights into the tail behavior of a distribution.

Port-Estimation of a Shape Second-Order Parameter
In this paper we study, under a semi-parametric framework and for heavy right tails, a class of location invariant estimators of a shape second-order parameter, ruling the rate of convergence of the normalised sequence of maximum values to a non ...

Asymptotic properties of isometries
Let \((X,d_1)\) and \((Y,d_2)\) be metric spaces. If \(I: X\to Y\) satisfies the equation \[ d_2[I(x), I(y)]= d_1(x,y) \] for all \(x,y\in X\), then \(I\) is called an isometry. Following Ulam and Hyers we call a mapping \(f: X\to Y\) an \(\varepsilon\)-isometry if \(f\) satisfies the inequality \[ | d_2[f(x), f(y)]- d_1(x,y)|\leq \varepsilon \] for ...

On the Estimation of the Second Order Parameter for Heavy-Tailed Distributions
The extreme-value index γ is an important parameter in extreme-value theory since it controls the first order behavior of the distribution tail. In the literature, numerous estimators of this parameter have been proposed especially in the case of heavy ...

Asymptotic Properties of Gaussian Processes
Abstract : The authors consider two problems for separable mean zero Gaussian processes X(t) with correlation functions rho(t,s) for which 1-rho(t,s) is asymptotic to a regularly varying (at zero) function of /t-s/ with exponent 0=or < alpha =or

Asymptotic invariants of lattices in locally compact groups
The aim of this work is to understand some of the asymptotic properties of sequences of lattices in a fixed locally compact group. In particular we will study the asymptotic growth of the Betti numbers of the lattices renormalized by the covolume and the
