Extreme Value Analysis of Statistically Independent Stochastic Variables [PDF]
한국해양공학회지, 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.

Extreme Value Analysis of Tide Gauge Record at the Port of Busan, South Korea
GeoHazards, 2023 This article conducts an extreme value analysis (EVA) of hourly tide gauge measurements at Busan, South Korea, from 1960 onwards to understand the influence of typhoon-driven surges and predicted tides that super-elevate ocean still water levels (SWLs ...

Statistical Modeling on the Severity of Unhealthy Air Pollution Events in Malaysia
Mathematics, 2022 This study proposes the concept of severity as an alternative measure of extreme air pollution events. Information about severity can be derived from the cumulative effect of air pollution events, which can be determined from unhealthy Air Pollution ...

Extreme Value Analysis for Mixture Models with Heavy-Tailed Impurity
Mathematics, 2021 This paper deals with the extreme value analysis for the triangular arrays which appear when some parameters of the mixture model vary as the number of observations grows.

Operating at the extreme: estimating the upper yield boundary of winter wheat production in commercial practice [PDF]
Royal Society Open Science, 2020 Wheat farming provides 28.5% of global cereal production. After steady growth in average crop yield from 1950 to 1990, wheat yields have generally stagnated, which prompts the question of whether further improvements are possible.

Threshold selection in univariate extreme value analysis [PDF]
Extremes, 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
Journal 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
Climate 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]
Extremes, 2022 AbstractThis 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 that the limiting ...

An improved method of extreme value analysis
Journal 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 ...
