The Semi-Hyperbolic Distribution and Its Applications
Stats, 2023 This paper studies a subclass of the class of generalized hyperbolic distribution called the semi-hyperbolic distribution. We obtain analytical expressions for the cumulative distribution function and, specifically, their first and second lower partial ...

Advances in Meteorology, 2023 The doubt in the calculation algorithm of the standardized precipitation index (SPI), which is widely preferred in the evaluation and monitoring of drought, still remains up-to-date because its calculation process is performed in the form of ...

On Generalized Gamma Distribution and Its Application to Survival Data
International Journal of Statistics and Probability, 2019 The generalized gamma distribution is a continuous probability distribution with three parameters. It is a generalization of the two-parameter gamma distribution.

Chebyshev–Edgeworth-Type Approximations for Statistics Based on Samples with Random Sizes
Mathematics, 2021 Second-order Chebyshev–Edgeworth expansions are derived for various statistics from samples with random sample sizes, where the asymptotic laws are scale mixtures of the standard normal or chi-square distributions with scale mixing gamma or inverse ...

Determination of best-fit probability distribution of annual maximum daily precipitation (Case study- Isfahan and Kashan stations) [PDF]
ریاضی و جامعه, 2022 The goal of this paper is to determine the best-fit probability distribution to describe the annual maximum daily rainfall for the Isfahan (period 1951-2010) and Kashan (period 1966-2010) stations located distantly in Isfahan province as an arid ...

A Bivariate Generalization of Gamma Distribution [PDF]
Communications in Statistics - Theory and Methods, 2013 In this article, a bivariate generalisation of the gamma distribution is proposed by using an unsymmetrical bivariate characteristic function; an extension to the non central case also receives attention. The probability density functions of the product and ratio of the correlated components of this distribution are also derived.

Two-pion light-cone distribution amplitudes from the instanton vacuum [PDF]
, 1998 We calculate the two-pion light-cone distribution amplitudes in the effective low-energy theory based on the instanton vacuum. These generalized distribution amplitudes describe the soft (non-perturbative) part of the process $\gamma^*\gamma \to \pi\pi ...

Complexity, 2021 In the absence of a correct distribution theory for complex data, neutrosophic algebra can be very useful in quantifying uncertainty. In applied data analysis, implementation of existing gamma distribution becomes inadequate for some applications when ...

On the Accuracy of the Generalized Gamma Approximation to Generalized Negative Binomial Random Sums
Mathematics, 2021 We investigate the proximity in terms of zeta-structured metrics of generalized negative binomial random sums to generalized gamma distribution with the corresponding parameters, extending thus the zeta-structured estimates of the rate of convergence in ...
