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...

Priority-Based Stippling and its Stylization Applications
Mould, David; Li, Hua - In: International Journal of Creative Interfaces and … 8 (2017) 2, pp. 31-53
This article presents a new and efficient automatic method for structure-preserving stippling. The core idea is to concentrate on structure preservation by using a priority-based scheme that treats extremal pixels first and preferentially assigns positive error to lighter pixels and negative...

Integrating Systems Modelling and Data Science: The Joint Future of Simulation and ‘Big Data' Science
Pruyt, Erik - In: International Journal of System Dynamics Applications … 5 (2016) 1, pp. 1-16
Although System Dynamics modelling is sometimes referred to as data-poor modelling, it often is –or could be– applied in a data-rich manner. However, more can be done in the era of ‘big data'. Big data refers here to situations with much more available data than was until recently...
