A New Heavy-Tailed Lomax Model With Characterizations, Applications, Peaks Over Random Threshold Value-at-Risk, and the Mean-of-Order-P Analysis
Autor: M. I. Khan, Abdussalam Aljadani, Mahmoud M. Mansour, Enayat M. Abd Elrazik, G. G. Hamedani, Haitham M. Yousof, Wahid A. M. Shehata
Publikováno v: Journal of Mathematics, Vol 2024 (2024)
In this work, a new heavy-tailed Lomax model is proposed for the reliability and actuarial risk analysis. Simulations are conducted to investigate how the estimators behave. Parameters are derived through maximum likelihood estimation techniques. The

Autor: Wahid A. M. Shehata, Nadeem Shafique Butt, Haitham Yousof, Mohamed Aboraya
Publikováno v: Pakistan Journal of Statistics and Operation Research. :249-272
In this article, we introduce a new generalization of the Exponentiated Exponential distribution. Various structural mathematical properties are derived. Numerical analysis for mean, variance, skewness and kurtosis and the dispersion index are perfor

The four-parameter exponentiated Weibull model with Copula, properties and real data modeling
Autor: Wahid A. M. Shehata, Haitham M. Yousof
Publikováno v: Pakistan Journal of Statistics and Operation Research. :649-667
A new four-parameter lifetime model is introduced and studied. The new model derives its flexibility and wide applicability from the well-known exponentiated Weibull model. Many bivariate and the multivariate type versions are derived using the Morge

A Modified Chi-square Type Test Statistic for the Double Burr X Model with Applications to Right Censored Medical and Reliability Data
Autor: Mohamed Nabil Fathy Ibrahim, Haitham M. Yousof, Wahid A. M. Shehata, Nadeem Shafique Butt, M. Masoom Ali, Khaoula Aidi
Publikováno v: Pakistan Journal of Statistics and Operation Research. :615-623
A new modified version of the Bagdonavičius-Nikulin goodness-of-fit test statistic is presented for validity for the right censor case under the double Burr type X distribution. The maximum likelihood estimation method in censored data case is used

A New Lifetime Model: Copulas, Properties and Real Lifetime Data Applications
Autor: Wahid A. M. Shehata
Publikováno v: Pakistan Journal of Statistics and Operation Research. :195-211
A new four parameter lifetime model called the Weibullgeneralized Lomax is proposed and studied. The new density function can be "right skewed", "symmetric" and "left skewed" and its corresponding failure rate function can be "monotonically decreasin
