The Exponentiated Generalized-G Poisson Family of Distributions
Aryal, Gokarna R.; Yousof, Haitham M. - In: Stochastics and Quality Control 32 (2017) 1, pp. 7-23
Abstract In this article we propose and study a new family of distributions which is defined by using the genesis of the truncated Poisson distribution and the exponentiated generalized-G distribution. Some mathematical properties of the new family including ordinary and incomplete moments,...

Estimation of Reliability in Multicomponent Stress-Strength Based on Dagum Distribution
Fulment, Arnold K.; Josephat, Peter K.; Srinivasa Rao, Gadde - In: Stochastics and Quality Control 32 (2017) 2, pp. 77-85
Abstract We consider the Dagum distribution for estimating the reliability of a k -component stress-strength system with different shape values of the shape parameter. We assume that the system has strength modelled by k independent and identically distributed random variables, and each...

Cubic Transmuted-G Family of Distributions and Its Properties
Aslam, Muhammad; Hussain, Zawar; Asghar, Zahid - In: Stochastics and Quality Control 33 (2018) 2, pp. 103-112
Abstract In this article, a new family of distributions is introduced by using transmutation maps. The proposed family of distributions is expected to be useful in modeling real data sets. The genesis of the proposed family, including several statistical and reliability properties, is presented....

On Extended Quadratic Hazard Rate Distribution: Development, Properties, Characterizations and Applications
Bhatti, Fiaz Ahmad; Hamedani, G. G.; Sheng, Wenhui; … - In: Stochastics and Quality Control 33 (2018) 1, pp. 45-60
Abstract In this paper, we propose a flexible extended quadratic hazard rate (EQHR) distribution with increasing, decreasing, bathtub and upside-down bathtub hazard rate function. The EQHR density is arc, right-skewed and symmetrical shaped. This distribution is also obtained from compounding...

The Reflected-Shifted-Truncated Lindley Distribution with Applications
Dey, Sanku; Waymyers, Sophia; Kumar, Devendra - In: Stochastics and Quality Control 35 (2020) 2, pp. 67-77
Abstract In this paper, a new probability density function with bounded domain is presented. The new distribution arises from the Lindley distribution proposed in 1958. It presents the advantage of not including any special function in its formulation. The new transformed model, called the...

Penalised likelihood methods for phase-type dimension selection
Albrecher, Hansjörg; Bladt, Martin; Müller, Alaric J. A. - In: Statistics & Risk Modeling 39 (2022) 3-4, pp. 75-92
Abstract Phase-type distributions are dense in the class of distributions on the positive real line, and their flexibility and closed-form formulas in terms of matrix calculus allow fitting models to data in various application areas. However, the parameters are in general non-identifiable, and...

On the Use of Projection Methods in the Computation of OLG Models / Zur Berechnung von OLG-Modellen mit Hilfe von Projektionsmethoden
Heer, Burkhard; Trede, Mark - In: Jahrbücher für Nationalökonomie und Statistik 220 (2000) 1, pp. 32-47
Summary We compare projection methods with the standard value function grid algorithm in order to solve overlapping generations models. We apply the methods to a particular 60-period OLG model with elastic labor supply in order to study the effects of unfunded public pensions on aggregate...

Using Inter-Block Synchronization to Improve the Knapsack Problem on GPUs
Sun, Xue; Wu, Chao-Chin; Chen, Liang-Rui; Lin, Jian-You - In: International Journal of Grid and High Performance … 10 (2018) 4, pp. 83-98
This article describes how as one of the hot parallel processors, the general-purpose graphics processing unit (GPU) has been widely adopted to accelerate various time-consuming algorithms. Dynamic programming (DP) optimization is a popular method to solve a particular class of complex problems....

Intertemporal Stable Pension Funding
Miao, Jerry C.Y.; Wang, Jennifer L. - In: Asia-Pacific Journal of Risk and Insurance 1 (2006) 2
This paper proposes a discrete dynamic programming model to maintain pension contribution in a stable level. By assuming an intertemporal stable contribution rate, we derive an algorithm to calculate the optimal contribution that requires less exogenous information and produces more stable...
