A Blockwise Empirical Likelihood Test for Gaussianity in Stationary Autoregressive Processes

open access: yesMathematics, 2023
A new and simple blockwise empirical likelihood moment-based procedure to test if a stationary autoregressive process is Gaussian has been proposed. The proposed test utilizes the skewness and kurtosis moment constraints to develop the test statistic ...

Gaussian approximation of suprema of empirical processes [PDF]

open access: yes, 2012
This paper develops a new direct approach to approximating suprema of general empirical processes by a sequence of suprema of Gaussian processes, without taking the route of approximating whole empirical processes in the sup-norm.

Improving Probability-Weighted Moment Methods for the Generalized Extreme Value Distribution

open access: yesRevstat Statistical Journal, 2008
In 1985 Hosking et al. estimated with the so-called Probability-Weighted Moments (PWM) method the parameters of the Generalized Extreme Value (GEV) distribution, the latter being classically fitted to maxima of sequences of independent and identically ...

Profiles of Burnout, Coping Strategies and Depressive Symptomatology

open access: yesFrontiers in Psychology, 2020
Burnout syndrome is has been associated with mental health problems such as depression, anxiety, and stress. Given this fact, some teachers implement various coping strategies for emotional control that are not always functional to mitigate such ...

Influence of Lubrication and Cooling on the Quality of Single-Point Incremental Forming Parts of Polycarbonate Sheets

open access: yesJournal of Manufacturing and Materials Processing, 2021
Without ensuring high productivity, single-point incremental forming allows obtaining cavities in sheet-type workpieces by rotating and moving a rotary forming tool along a predetermined path. The process can be used in the case of both metal and plastic

Hierarchical effects facilitate spreading processes on synthetic and empirical multilayer networks.

open access: yesPLoS ONE, 2021
In this paper we consider the effects of corporate hierarchies on innovation spread across multilayer networks, modeled by an elaborated SIR framework. We show that the addition of management layers can significantly improve spreading processes on both ...

An Interdisciplinary Perspective Towards Explaining the Visual Aesthetic Experience: The Case of Emotion

open access: yesItinera, 2022
This paper discusses the empirical findings concerning the visual aesthetic experience in a neurological context. Accordingly, the aim of this paper is to shed light on the common ground across neuroscience, psychology, and philosophy to pave new ...

The Volatility Processes In Indonesia’s Demand For Narrow Money

open access: yesEconomic Journal of Emerging Markets, 2009
There were two purposes of this research. The first purpose was to test and search the volatility processes by using ARCH/GARCH methodology in Indonesia’s demand for narrow money estimation, which was approached by error correction modeling (ECM).

A Discrete Cramér–Von Mises Statistic Related to Hahn Polynomials with Application to Goodness-of-Fit Testing for Hypergeometric Distributions

open access: yesAxioms
We give the Karhunen–Loève expansion of the covariance function of a family of discrete weighted Brownian bridges, appearing as discrete analogues of continuous Gaussian processes related to Cramér –von Mises and Anderson–Darling statistics. This analogy

Conditional Empirical Processes

open access: yesThe Annals of Statistics, 1986
Let \((X_ 1,Y_ 1),(X_ 2,Y_ 2),..\). be a sequence of independent identically distributed random vectors such that \(X_ n\) and \(Y_ n\) take values in R and \(R^ d\), \(d\geq 1\), respectively. In the case where \(d=1\), the author [ibid. 12, 917-926 (1984; Zbl 0539.62026)] introduced a nearest-neighbour-type estimate for the regression function \(E(Y|
