Spatial Modeling of Extreme Temperature in Northeast Thailand

open access: yesAtmosphere, 2022
The objective of the present study was to examine and predict the annual maximum temperature in the northeast of Thailand by using data from 25 stations and employing spatial extreme modeling which is based on max-stable process (MSP) using schlatter’s ...

Return Period Evaluation of the Largest Possible Earthquake Magnitudes in Mainland China Based on Extreme Value Theory

open access: yesSensors, 2021
The largest possible earthquake magnitude based on geographical characteristics for a selected return period is required in earthquake engineering, disaster management, and insurance. Ground-based observations combined with statistical analyses may offer

Seismic risk in the east of the Bayan Har block based on the POT model

open access: yesGeomatics, Natural Hazards & Risk, 2022
This article elaborates on a peaks over threshold (POT) model with earthquake samples based on the Pareto distribution. We analyze the earthquakes using the POT model in the eastern Bayan Har block.

Modelling of extreme minimum rainfall using generalised extreme value distribution for Zimbabwe

open access: yesSouth African Journal of Science, 2015
We modelled the mean annual rainfall for data recorded in Zimbabwe from 1901 to 2009. Extreme value theory was used to estimate the probabilities of meteorological droughts.

基于轮廓似然估计的广义极值分布在地震中长期预测中的应用

open access: yesDizhen xuebao, 2022
为描述强震预测的不确定性,在地震预报极值分析模型的参数估计中,引入轮廓似然估计法。对广义极值分布中形状参数和地震重现水平的轮廓似然估计原理及数值算法进行了详细地阐述,并利用构建的广义极值分布模型对东昆仑地震带进行了地震危险性分析。关于形状参数和重现水平的点估计,以及10年以内的重现水平置信区间的估计,轮廓似然估计法与极大似然估计法效果基本相同,但在中长期地震重现水平置信区间的预测中,轮廓似然估计法得到的关于置信水平不对称的置信区间,在强震水平下对预测震级的不确定性表达更准确,预测结果更加有效。

The Persistence of Abnormal Returns at Industry and Firm Levels [PDF]

open access: yesSSRN Electronic Journal, 2003
The present paper proposes a model for the persistence of abnormal returnsboth at firm and industry levels, when longitudinal data for the profitsof firms classiffied as industries are available. The model produces a two-way variance decomposition of abnormal returns: (a) at firm versus industrylevels, and (b) for permanent versus transitory components.

REVERSE LOGISTICS RETAIL LEVEL RETURN

open access: yesINTERNATIONAL JOURNAL FOR TRAFFIC AND TRANSPORT ENGINEERING, 2014
Conducting scientific research regarding reverse logistics systems includes certain difficulties. Developed logistics systems are aimed at analysing reverse logistics issues and tend to continuously detect differences and oscillations in the flow of returned products and their characteristics.

Return levels of temperature extremes in southern Pakistan [PDF]

open access: yesEarth System Dynamics, 2017
Abstract. Southern Pakistan (Sindh) is one of the hottest regions in the world and is highly vulnerable to temperature extremes. In order to improve rural and urban planning, it is useful to gather information about the recurrence of temperature extremes.
