"Long-run Behavior of Macroeconomic Models with Heterogeneous Agents: Asymptotic Behavior of One- and Two-Parameter Poisson-Dirichlet Distributions" [PDF]

open access: yes
This paper discusses a symptotic behavior of one-and two-parameter Poisson-Dirichlet models, that is, Ewens models and its two parameter extensions by Pitman, and show that their a symptotic behavior arevery different.

Statistical Analysis of a Telephone Call Center: A Queueing-Science Perspective [PDF]

open access: yes
A call center is a service network in which agents provide telephone-based services. Customers that seek these services are delayed in tele-queues. This paper summarizes an analysis of a unique record of call center operations.

Anisotropy of the sky distribution of gamma-ray bursts

open access: yes, 1998
The isotropy of gamma-ray bursts collected in current BATSE catalog is studied. It is shown that the quadrupole term being proportional to \sim sin 2b sin l is non-zero with a probability of 99.9%. The occurrence of this anisotropy term is then confirmed

Estimation of excess hazard using compound Poisson frailty model

open access: yesJournal of Biostatistics and Epidemiology, 2015
Background & Aim: The excess hazard rate proposed by Andersen and Vaeth may underestimate the long-term excess hazard rate for cancer survival. Zahl explained the phenomenon by continuous selection of the most robust individuals after diagnosis.

An extended Poisson distribution

open access: yes, 2013
The Poisson distribution is extended over the set of all integers. The motivation comes from the many reflected versions of the gamma distribution, the continuous analog of the Poisson distribution, defined over the entire real line. Various mathematical

Zero-Truncated Poisson Exponentiated Gamma Distribution: Application and Estimation Methods

open access: yes, 2019
We define a new two-parameter lifetime model called the zero-truncated Poisson exponentiated gamma distribution. The hazard function of the new distribution has monotonic and non-monotonic shapes, which allows to fit more dispersed data.

Mixed Poisson Processes with Dropout for Consumer Studies

open access: yesStats
We adapt the classical mixed Poisson process models for investigation of consumer behaviour in a situation where after a random time we can no longer identify a customer despite the customer remaining in the panel and continuing to perform buying actions.

Linear and Quadratic Functionals of RandomHazard rates: an Asymptotic Analysis [PDF]

open access: yes
A popular Bayesian nonparametric approach to survival analysis consists in modeling hazard rates as kernel mixtures driven by a completely random measure.

The Poisson-Lomax Distribution [PDF]

open access: yes, 2014
In this paper we propose a new three-parameter lifetime distribution with upside-down bathtub shaped failure rate. The distribution is a compound distribution of the zero-truncated Poisson and the Lomax distributions (PLD). The density function, shape of
