Threshold selection in univariate extreme value analysis [PDF]

open access: yesExtremes, 2021
AbstractThreshold selection plays a key role in various aspects of statistical inference of rare events. In this work, two new threshold selection methods are introduced. The first approach measures the fit of the exponential approximation above a threshold and achieves good performance in small samples.

Extreme-value analysis of wave heights

open access: yesJournal of Research of the National Institute of Standards and Technology, 1994
This paper discusses the most common problems associated with the determination of design wave heights. It analyzes two common methods used in fitting wave data and shows some of the stability or inconsistency problems associated with commonly used distributions.

The probability of unprecedented high rainfall in wine regions of northern Portugal

open access: yesClimate Services, 2023
Climate is arguably one of the most important factors determining the quality of wine from any given grapevine variety. This study focuses on three wine-growing regions in northern Portugal: Vinho Verde, Trás-os-Montes and Douro, the latter coinciding ...

Regression-type analysis for multivariate extreme values [PDF]

open access: yesExtremes, 2022
Abstract This paper devises a regression-type model for the situation where both the response and covariates are extreme. The proposed approach is designed for the setting where the response and covariates are modeled as multivariate extreme values, and thus contrarily to standard regression methods it takes into account the key fact ...

An improved method of extreme value analysis

open access: yesJournal of Hydrology X, 2019
An improved method to estimate the probability of extreme events from independent observations is presented. The method, called VWLS, is based on minimizing the variance of order-ranked observations plotted according to their true probability and ...

The Global Wind Resource Observed by Scatterometer

open access: yesRemote Sensing, 2020
A 27-year-long calibrated multi-mission scatterometer data set is used to determine the global basin-scale and near-coastal wind resource. In addition to mean and percentile values, the analysis also determines the global values of both 50- and 100-year ...

Extreme Value Analysis of Ocean Still Water Levels along the USA East Coast—Case Study (Key West, Florida)

open access: yesCoasts, 2023
This paper provides an Extreme Value Analysis (EVA) of the hourly still water level (SWL) record at Key West, Florida dating back to 1913 to understand the statistical likelihood of the combination of high predicted tides and the more dynamic influences (

Estimation of Return Levels for Extreme Skew Surge Coastal Flooding Events in the Delaware and Chesapeake Bays for 1980–2019

open access: yesFrontiers in Climate, 2021
Extreme storm surges can overwhelm many coastal flooding protection measures in place and cause severe damages to private communities, public infrastructure, and natural ecosystems.

Bayesian Variable Selection in Generalized Extreme Value Regression: Modeling Annual Maximum Temperature

open access: yesMathematics, 2023
In many applications, interest focuses on assessing relationships between covariates and the extremes of the distribution of a continuous response. For example, in climate studies, a usual approach to assess climate change has been based on the analysis ...

Impact of ASOS Real-Time Quality Control on Convective Gust Extremes in the USA

open access: yesMeteorology, 2023
Most damage to buildings across the contiguous United States, in terms of number and total cost, is caused by gusts in convective events associated with thunderstorms. Their assessment relies on the integrity of meteorological observations.
