Minimum Sample Size Determination for Generalized Extreme Value Distribution

open access: yesCommunications in Statistics - Simulation and Computation, 2010
Sample size determination is an important issue in statistical analysis. Obviously, the larger the sample size is, the better the statistical results we have. However, in many areas such as coastal engineering and environmental sciences, it can be very expensive or even impossible to collect large samples. In this paper, we propose a general method for

Spatial Patterns in the Extreme Dependence of Ozone Pollution between Cities in China’s BTH Region

open access: yesAtmosphere, 2023
Ozone pollution in China has become increasingly severe in recent years. Considering the damage that extreme ozone pollution may cause and the fact that the occurrence of extreme ozone pollution among different locations may be related, this paper uses ...

Evaluation of the best fit distribution for partial duration series of daily rainfall in Madinah, western Saudi Arabia [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2014
Rainfall frequency analysis is an essential tool for the design of water related infrastructure. It can be used to predict future flood magnitudes for a given magnitude and frequency of extreme rainfall events.

Bayesian modeling of dynamic extreme values: extension of generalized extreme value distributions with latent stochastic processes [PDF]

open access: yesJournal of Applied Statistics, 2016
ABSTRACTThis paper develops Bayesian inference of extreme value models with a flexible time-dependent latent structure. The generalized extreme value distribution is utilized to incorporate state variables that follow an autoregressive moving average (ARMA) process with Gumbel-distributed innovations.

Cramer-von Mises and Anderson-Darling goodness of fit tests for extreme value distributions with unknown parameters [PDF]

open access: yes, 2004
The use of goodness of fit tests based on Cramer-von Mises and Anderson-Darling statistics is discussed, with reference to the composite hypothesis that a sample of observations comes from a distribution, FH, whose parameters are unspecified.

On the maximum likelihood estimator for the Generalized Extreme-Value distribution [PDF]

open access: yesExtremes, 2017
The vanilla method in univariate extreme-value theory consists of fitting the three-parameter Generalized Extreme-Value (GEV) distribution to a sample of block maxima. Despite claims to the contrary, the asymptotic normality of the maximum likelihood estimator has never been established.

Posterior propriety in Bayesian extreme value analyses using reference priors [PDF]

open access: yes, 2015
The Generalized Pareto (GP) and Generalized extreme value (GEV) distributions play an important role in extreme value analyses, as models for threshold excesses and block maxima respectively. For each of these distributions we consider Bayesian inference

Flood Frequency Analyses over Different Basin Scales in the Blue Nile River Basin, Ethiopia

open access: yesHydrology, 2020
The frequency and intensity of flood quantiles and its attendant damage in agricultural establishments have generated a lot of issues in Ethiopia. Moreover, precise estimates of flood quantiles are needed for efficient design of hydraulic structures ...

Extreme Value Analysis of Statistically Independent Stochastic Variables [PDF]

open access: yes한국해양공학회지, 2019
An extreme value analysis (EVA) is essential to obtain a design value for highly nonlinear variables such as long-term environmental data for wind and waves, and slamming or sloshing impact pressures.
