On the Topp Leone Exponentiated-G Family of Distributions: Properties and Applications

Sule Ibrahim, Sani Ibrahim Doguwa, Isah Audu & Jibril Haruna Muhammad · Asian Journal of Probability and Statistics · 2020

We proposed a new family of distributions called the Topp Leone exponentiated-G family of distributions with two extra positive shape parameters, which generalizes and also extends the Topp Leone-G family of distributions. We derived some mathematical properties of the proposed f...

Estimating the Number of Patents in the World Using Count Panel Data Models

Ahmed H. Youssef, Mohamed R. Abonazel & Elsayed G. Ahmed · Asian Journal of Probability and Statistics · 2020

In this paper, we review some estimators of count regression (Poisson and negative binomial) models in panel data modeling.  These estimators based on the type of the panel data model (the model with fixed or random effects). Moreover, we study and compare the performance of thes...

Second Order Slope Rotatable Designs under Tri-diagonal Correlation Structure of Errors Using a Pair of Incomplete Block Designs

B. Sulochana & B. Re. Victorbabu · Asian Journal of Probability and Statistics · 2020

Box and Hunter [1] introduced the concept of rotatability for response surface designs. The concept of slope-rotatability was introduced by Hader and Park [2] as an analogous to rotatability property, which is an important design criterion for response surface design. Slope-rotat...

On Model Comparison: Application of Savage-Dickey Density Ratio to Bayes Factor

Olawale B. Akanbi, Olusanya E. Olubusoye & Samuel A. Babatunde · Asian Journal of Probability and Statistics · 2020

Bayes factor is a major Bayesian tool for model comparison especially when the model priors are the same. In this paper, the Savage-Dickey Density Ratio (SDDR) is used to derive the Bayes factor to select a model from two competing models under consideration in a normal linear re...
