On Characterization of Gompertz Distribution by Properties of Generalized Record Values [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2014
In this chapter, we derive some recurrence relations satisfied by single and product moments of generalized record values arising from Gompertz and inverted Gompertz distributions.

Relations for Moments of Generalised Order Statistics Based on Weibull-G Family of Distributions [PDF]

open access: yesOperations Research and Decisions, 2022
The Weibull distribution is one of the important distributions used in reliability theory and life-testing experiments. The generalised versions of the Weibull distribution give a more flexible model for these studies.

An obstruction for q-deformation of the convolution product [PDF]

open access: yes, 1996
We consider two independent q-Gaussian random variables X and Y and a function f chosen in such a way that f(X) and X have the same distribution. For 0 < q < 1 we find that at least the fourth moments of X + Y and f(X) + Y are different. We conclude that

On the Burr XII-moment exponential distribution.

open access: yesPLoS ONE, 2021
In this study, a new flexible lifetime model called Burr XII moment exponential (BXII-ME) distribution is introduced. We derive some of its mathematical properties including the ordinary moments, conditional moments, reliability measures and ...

On the use of the l(2)-norm for texture analysis of polarimetric SAR data [PDF]

open access: yes, 2016
In this paper, the use of the l2-norm, or Span, of the scattering vectors is suggested for texture analysis of polarimetric synthetic aperture radar (SAR) data, with the benefits that we need neither an analysis of the polarimetric channels separately ...

Whitehead products in moment-angle complexes [PDF]

open access: yesJournal of the Mathematical Society of Japan, 2020
In toric topology, to a simplicial complex $K$ with $m$ vertices, one associates two spaces, the moment-angle complex $\mathcal{Z}_K$ and the Davis-Januszkiewicz space $DJ_K$. These spaces are connected by a homotopy fibration $\mathcal{Z}_K\to DJ_K\to(\mathbb{C}P^\infty)^m$.

Record values from a family of J-shaped distributions

open access: yesStatistica, 2013
A family of J-shaped distributions has applications in life testing modeling. In this paper we study record values from this family of distributions. Based on lower records, recurrence relations and bounds as well as expressions for moments and product ...

Solar ν ¯ e $$ {\overline{\nu}}_e $$ flux: revisiting bounds on neutrino magnetic moments and solar magnetic field

open access: yesJournal of High Energy Physics, 2022
The interaction of neutrino transition magnetic dipole moments with magnetic fields can give rise to the phenomenon of neutrino spin-flavour precession (SFP).

Random permutation matrices under the generalized Ewens measure [PDF]

open access: yes, 2013
We consider a generalization of the Ewens measure for the symmetric group, calculating moments of the characteristic polynomial and similar multiplicative statistics.

Characterization and Simulation of Transient Vibrations Using Band Limited Temporal Moments

open access: yesShock and Vibration, 1994
A method is described to characterize shocks (transient time histories) in terms of the Fourier energy spectrum and the temporal moments of the shock passed through a contiguous set of band pass filters.
