Response distribution of nonlinear systems subjected to non-Gaussian random excitation using Gaussian mixture model

Nihon Kikai Gakkai ronbunshu, 2015
The method using Gaussian mixture model and moment equations is developed to obtain the probability density of the stationary response of a nonlinear system subjected to non-Gaussian random excitation.

Association Measures in the Bivariate Correlated Frailty Model

Revstat Statistical Journal, 2018
This paper deals with a general bivariate correlated frailty model. This includes the multiplicative as well as the additive frailty effect. The association parameter is studied for the shared as well as the general correlated model. The results for the

Structural properties of size biased Gamma distribution

, 2013
In this paper, a new class of size-biased Gamma distribution is derived. A size-biased gamma distribution, a particular case of weighted gamma distribution, taking the weights as the variate values has been defined. A new distribution which contains as a

On gamma Inverse Weibull Distribution

Journal of the National Science Foundation of Sri Lanka, 2019
The inverse Weibull distribution which was first introduced to investigate the decay of mechanical components is widely used in the field of biology, especially in the areas of survival and reliability analysis. In this paper, a generalisation of inverse Weibull distribution is presented using a new class of gamma distributions. For the proposed model,

Inequalities for the median of the gamma distribution

Journal of Computational and Applied Mathematics, 2009
AbstractWe provide several new inequalities involving λn, the median of the gamma distribution of order n+1 with parameter 1. Among others, we present sharp upper and lower bounds for the arithmetic mean of λ1,λ2,…,λn.

Dynamic Keynesian Model of Economic Growth with Memory and Lag

Mathematics, 2019
A mathematical model of economic growth with fading memory and continuous distribution of delay time is suggested. This model can be considered as a generalization of the standard Keynesian macroeconomic model.

Statistical modeling of space shuttle environmental data [PDF]

Statistical models which use a class of bivariate gamma distribution are examined. Topics discussed include: (1) the ratio of positively correlated gamma varieties; (2) a method to determine if unequal shape parameters are necessary in bivariate gamma ...

Some bivariate gamma distributions

Applied Mathematics Letters, 2006
AbstractWe introduce two new bivariate gamma distributions based on a characterizing property involving products of gamma and beta random variables. We derive various representations for their joint densities, product moments, conditional densities and conditional moments.

Bayesian Methods for Step-Stress Accelerated Test under Gamma Distribution with a Useful Reparametrization and an Industrial Data Application

Mathematics
This paper presents a multiple step-stress accelerated life test using type II censoring. Assuming that the lifetimes of the test item follow the gamma distribution, the maximum likelihood estimation and Bayesian approaches are used to estimate the ...
