New extreme value theory for maxima of maxima

open access: yesStatistical Theory and Related Fields, 2021
Although advanced statistical models have been proposed to fit complex data better, the advances of science and technology have generated more complex data, e.g., Big Data, in which existing probability theory and statistical models find their ...

Stable distributions in fragmentation processes [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 1996
We introduce three models of fragmentation in which the largest fragment in the system can be broken at each time step with a fixed probability, p. We solve these models exactly in the long time limit to reveal stable time invariant (scaling) solutions which depend on p and the precise details of the fragmentation process.

Metcalfe's law and log-period power laws in the cryptocurrencies market

open access: yesEconomics: Journal Articles, 2019
In this paper the authors investigate the statistical properties of some cryptocurrencies by using three layers of analysis: alpha-stable distributions, Metcalfe’s law and the bubble behaviour through the LPPL modelling.

Tsallis Relative Entropy and Anomalous Diffusion

open access: yesEntropy, 2012
In this paper we utilize the Tsallis relative entropy, a generalization of the Kullback–Leibler entropy in the frame work of non-extensive thermodynamics to analyze the properties of anomalous diffusion processes.

Species Composition, Growth, and Trophic Traits of Hairtail (Trichiuridae), the Most Productive Fish in Chinese Marine Fishery

open access: yesAnimals, 2022
Hairtail (Scombriformes: Trichiuridae) have always ranked first in single-species production in Chinese marine fishery. However, due to the confusion of species identification, in official statistics, data on hairtail production and economic value are a ...

The Alpha stable distribution in ocean ambient noise modelling [PDF]

open access: yesMATEC Web of Conferences, 2019
In view of the non-Gaussian of ocean ambient noise, the  stable distribution is applied to the statistical modelling. Firstly, the one-to-one correspondence between the four parameters of stable distribution and the sample mean, variance, skewness and ...

Estimation of the parameters of multivariate stable distributions [PDF]

open access: yesCommunications in Statistics - Simulation and Computation, 2020
In this paper, we begin our discussion with some of the well-known methods available in the literature for the estimation of the parameters of a univariate/multivariate stable distribution. Based on the available methods, a new hybrid method is proposed for the estimation of the parameters of a univariate stable distribution.

Building Mexican isoscapes: Oxygen and hydrogen isotope data of meteoric water sampled across Mexico

open access: yesData in Brief, 2021
Oxygen and hydrogen isotope data of meteoric water samples are compiled from several States across Mexico. This dataset includes 287 oxygen and hydrogen (and deuterium excess) isotope data corresponding to meteoric water collected from the surface ...

A Note on Distributed Stable Matching [PDF]

open access: yes2009 29th IEEE International Conference on Distributed Computing Systems, 2009
We consider the distributed complexity of the stable marriage problem. In this problem, the communication graph is undirected and bipartite, and each node ranks its neighbors. Given a matching of the nodes, a pair of nodes is called blocking if they prefer each other to their assigned match.

Testing Stock Return Distribution in the Tehran Stock Exchange [PDF]

open access: yesراهبرد مدیریت مالی, 2013
In the past several years many financial theories such as portfolio optimization model, model prices of capital assets (CAPM), arbitrage pricing, and the like, are based on normal return distribution.
