The Burr X Pareto distribution: properties, applications and VaR estimation
Korkmaz, Mustafa Çağatay; Altun, Emrah; Yousof, Haitham M.; Afify, Ahmed Z.; Nadarajah, Saralees (MDPI, 2018)In this paper, a new three-parameter Pareto distribution is introduced and studied. We discuss various mathematical and statistical properties of the new model. Some estimation methods of the model parameters are performed. ... -
The Weibull Marshall-Olkin family: Regression model and application to censored data
Korkmaz, Mustafa Çağatay; Cordeiro, Gauss M.; Yousof, Haitham M.; Pescim, Rodrigo R.; Afify, Ahmed Z.; Nadarajah, Saralee (Taylor & Francis Inc, 2019)We introduce a new class of distributions called the Weibull Marshall-Olkin-G family. We obtain some of its mathematical properties. The special models of this family provide bathtub-shaped, decreasing-increasing, ... -
The xgamma family: Censored regression modelling and applications
Cordeiro, Gauss M.; Altun, Emrah; Korkmaz, Mustafa Çağatay; Pescim, Rodrigo R.; Afify, Ahmed Z.; Yousof, Haitham M. (National Statistical Institute, 2020)In this paper, a new family of distributions with one extra shape parameter, called the xgamma-G, is proposed. comprehensive treatment of some of its mathematical properties including ordinary and incomplete moments and ...
