Extreme Value Analysis for Mixture Models with Heavy-Tailed Impurity

open access: yesMathematics, 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.

Extreme values in ionospheric radio propagation

open access: yesAnnals of Geophysics, 2002
Proposals are made for Earth-space and space-space paths to apply the term ?propagation degradation probability?, analogous to ?basic circuit reliability?

On the influence of variability of snow cover parameters to the ground freezing

open access: yesЛëд и снег, 2015
Depth and rate of the soil freezing are stronly determined by dynamics of snow accumulation during the first half of a cold season. Dynamics of snow accumulation over two periods (1966–2000 and 2001–2010) was analyzed using data of snow surveys performed

Improved Mixed Estimator Using Two Auxiliary Variables For Full Extreme Maximum And Minimum Values In Single Phase Sampling [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية
The use of multiple auxiliary variables has been established to improve precision in the estimators of ratio, regression and product respectively. However, the presence of extreme values in the distribution could annul such efficiency Olatayo et al ...

Extreme-value statistics of stochastic transport processes

open access: yesNew Journal of Physics, 2020
We derive exact expressions for the finite-time statistics of extrema (maximum and minimum) of the spatial displacement and the fluctuating entropy flow of biased random walks.

Estimating of the Proportional Hazard Premium for Heavy-Tailed Claim Amounts with the Pot Method

open access: yesRevstat Statistical Journal, 2012
In this paper we propose a new estimator of the proportional hazard premium for heavy-tailed claim amounts, with a help of the peak-over-threshold (POT) method.

A New Discrete Analog of the Continuous Lindley Distribution, with Reliability Applications

open access: yesEntropy, 2020
In this paper, we propose and study a new probability mass function by creating a natural discrete analog to the continuous Lindley distribution as a mixture of geometric and negative binomial distributions.

A New Parameter Estimator for the Generalized Pareto Distribution under the Peaks over Threshold Framework

open access: yesMathematics, 2019
Techniques used to analyze exceedances over a high threshold are in great demand for research in economics, environmental science, and other fields. The generalized Pareto distribution (GPD) has been widely used to fit observations exceeding the tail ...

Bayesian Inference in Extremes Using the Four-Parameter Kappa Distribution

open access: yesMathematics, 2020
Maximum likelihood estimation (MLE) of the four-parameter kappa distribution (K4D) is known to be occasionally unstable for small sample sizes and to be very sensitive to outliers.
