The Additive Weibull-Geometric Distribution: Theory and Applications [PDF]

Journal of Statistical Theory and Applications (JSTA), 2016
In this paper, we introduce a new class of lifetime distributions which is called the additive Weibull geometric (AWG) distribution. This distribution obtained by compounding the additive Weibull and geometric distributions.

An Entropy-Based Contagion Index and Its Sampling Properties for Landscape Analysis

Entropy, 2014
Studies of spatial patterns of landscapes are useful to quantify human impact, predict wildlife effects, or describe various landscape features. A robust landscape index should quantify two components of landscape diversity: composition and configuration.

Combinatorics of geometrically distributed random variables: new q-tangent and q-secant numbers

International Journal of Mathematics and Mathematical Sciences, 2000
Up-down permutations are counted by tangent (respectively, secant) numbers. Considering words instead, where the letters are produced by independent geometric distributions, there are several ways of introducing this concept; in the limit they all ...

Exponential-Discrete Generalized Exponential Distribution: A New Compound Model [PDF]

Journal of Statistical Theory and Applications (JSTA), 2016
In this paper, the researchers attempt to introduce a new generalization of the exponential distribution. This new model is obtained by compounding the exponential distribution and discrete generalized exponential distribution of a second type, which is ...

则木河、大凉山和小江断裂交会区断裂几何展布及运动特征研究

Dizhen xuebao
走滑断裂系的几何复杂段落可以影响大地震破裂的起始、扩展和结束，并最终决定了大地震破裂的长度和最大震级。四川宁南至云南巧家一带为青藏高原东边界则木河、大凉山和小江断裂的交会区，针对三条断裂曾开展过1 ∶ 5万活动断层填图工作，但对三条断裂的交切关系认识仍不充分，并且缺乏从断层系统的角度认识该地区断裂的几何展布和运动特征。本文针对断裂交会区开展了航片解译及详细的地质地貌调查，识别出小江断裂北段的走向在巧家以北发生约25°的偏转，形成了一个明显的弯曲构造；宁南盆地构成了则木河断裂和小江断裂的分段边界，为宽约4.

Weighted-Likelihood-Ratio-Based EWMA Schemes for Monitoring Geometric Distributions

Axioms
Monitoring the parameter of discrete distributions is common in industrial production. Also, it is often crucial to monitor the parameter of geometric distribution, which is often regarded as the nonconforming item rate.

Ruin probability analysis in geometric inhomogeneous claims case

Lietuvos Matematikos Rinkinys, 2011
The discrete time risk model with inhomogeneous claims is analyzed. The finite time ruin probability expression is obtained for the case when claims are distributed by geometric distribution with changing parameters.

A New Generalization of Weighted Geometric Distribution and its Properties [PDF]

Journal of Statistical Theory and Applications (JSTA), 2017
Discrete distributions are widely used to model lifetime for count data. In this paper we introduce a new generalization of weighted geometric (GWG) distribution with the weight function w(x) = (1−p^{αx})^β whose special case proposes a discrete ...
