A strong deviation theorem and its application to herding effect
Results in Applied Mathematics, 2020 Wang and Yang (2011) studied the strong deviation theorems of the n-th order identical distribution (for short i.d.) random sequences. In the present paper we arrive at the strong deviation theorems for the moving averages of the third order non ...

The Kumaraswamy-geometric distribution
Journal of Statistical Distributions and Applications, 2014 In this paper, the Kumaraswamy-geometric distribution, which is a member of the T-geometric family of discrete distributions is defined and studied. Some properties of the distribution such as moments, probability generating function, hazard and quantile

A novel approach to compare the spectral densities of some uncorrelated cyclostationary time series
Alexandria Engineering Journal, 2022 Our primary objective in this article is to compare the spectral densities of some cyclostationary time series. By using the limiting distributions of the discrete Fourier transform, a novel approach is introduced to determine whether the spectral ...

A great disturbance in the crypto: Understanding cryptocurrency returns under attacks
Blockchain: Research and Applications, 2021 A non-traditional type of financial asset, cryptocurrencies based on public blockchains are still little understood in their real-world behavior. Exogenous events such as cyber-attacks and their media coverage can strongly affect their supply and demand,

Technical and allocative inefficiency in production systems: a vine copula approach
Dependence Modeling, 2022 Modeling the error terms in stochastic frontier models of production systems requires multivariate distributions with certain characteristics. We argue that canonical vine copulas offer a natural way to model the pairwise dependence between the two main ...
