Estimation of parameters of Weibull–Gamma distribution based on progressively censored data

open access: yes, 2018
In this paper, the estimation of parameters of a three-parameter Weibull–Gamma distribution based on progressively type-II right censored sample is studied.

A New Family of Extended Lindley Models: Properties, Estimation and Applications

open access: yesMathematics, 2020
There are many proposed life models in the literature, based on Lindley distribution. In this paper, a unified approach is used to derive a general form for these life models.

Markov chain modeling of daily rainfall in Lay Gaint Woreda, South Gonder Zone, Ethiopia

open access: yesJournal of Degraded and Mining Lands Management, 2018
Information on seasonal Kiremet and seasonal Belg rainfall amount is important in the rain fed agriculture of Ethiopia since more than 85% of the population is dependent on agriculture particularly on rain fed farming practices.

The support of the limit distribution of optimal Riesz energy points on sets of revolution in $\mathbb{R}^{3}$

open access: yes, 2007
Let A be a compact set in the right-half plane and $\Gamma(A)$ the set in $\mathbb{R}^{3}$ obtained by rotating A about the vertical axis. We investigate the support of the limit distribution of minimal energy point charges on $\Gamma(A)$ that interact ...

Two-pion light-cone distribution amplitudes from the instanton vacuum [PDF]

open access: yes, 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 ...

The spatial distribution of dark-matter-annihilation originated gamma-ray line signal

open access: yes, 2013
The GeV$-$TeV $\gamma-$ray line signal is the smoking gun signature of the dark matter annihilation or decay. The detection of such a signal is one of the main targets of some space-based telescopes, including Fermi-LAT and the upcoming CALET, DAMPE and ...

Are There MeV Gamma-Ray Bursts? [PDF]

open access: yes, 1995
It is often stated that gamma-ray bursts (GRBs) have typical energies of several hundred keV. Is this a real feature of GRBs or is it due to an observational bias?

Harrod–Domar Growth Model with Memory and Distributed Lag

open access: yesAxioms, 2019
In this paper, we propose a macroeconomic growth model, in which we take into account memory with power-law fading and gamma distributed lag. This model is a generalization of the standard Harrod–Domar growth model.

A Note on Gamma Distributed Lags [PDF]

open access: yesInternational Economic Review, 1971
This paper talks about the Solow (10) generalized Koyck's method for distributed lags to a family of J-shaped or unimodel lag distributions given by the Pascal distributions. Jorgenson (5) advances it to what he calls the general Pascal distribution.
