A Gibbs Sampling Scheme for a Generalised Poisson-Kingman Class
Robert C. Griffiths, Ross A. Maller, Soudabeh Shemehsavar
A Bayesian nonparametric method of James, Lijoi \& Prunster (2009) used to predict future values of observations from normalized random measures with independent increments is modi…
Limiting Behaviour of Poisson-Dirichlet and Generalised Poisson-Dirichlet Distributions
Ross Maller, Soudabeh Shemehsavar
We derive large-sample and other limiting distributions of the ``frequency of frequencies'' vector, , together with the number of species, , in a Poisson-Dirichlet…
Failure Inference and Optimization for Step Stress Model Based on Bivariate Wiener Model
S. Shemehsavar, Morteza Amini
In this paper, we consider the situation under a life test, in which the failure time of the test units are not related deterministically to an observable stochastic time varying c…
Optimal design for step-stress accelerated test with random discrete stress elevating times based on gamma degradation process
Morteza Amini, Soudabeh Shemehsavar, Zhengqiang Pan
Recently, a step-stress accelerated degradation test (SSADT) plan, in which the stress level is elevated when the degradation value of a product crosses a pre-specified value, was…
