Bivariate Compound Exponentiated Survival Function of the Lomax Distribution: Estimation and Prediction

R. M. Refaey, G. R. AL-Dayian & A. A. EL-Helbawy · Asian Journal of Probability and Statistics · 2021

In this paper, bivariate compound exponentiated survival function of the Lomax distribution is constructed based on the technique considered by AL-Hussaini (2011). Some properties of the distribution are derived. Maximum likelihood estimation and prediction of the future observat...

Bivariate Burr Type III Distribution: Estimation and Prediction

A. A. M. Mahmoud, R. M. Refaey, G. R. AL-Dayian & A. A. EL-Helbawy · Journal of Advances in Mathematics and Computer Science · 2021

In this paper, a bivariate Burr Type III distribution is constructed and some of its statistical properties such as bivariate probability density function and its marginal, joint cumulative distribution and its marginal, reliability and hazard rate functions are studied. The join...

Bayesian Estimation and Prediction Based on Constant Stress-Partially Accelerated Life Testing for Topp Leone-Inverted Kumaraswamy Distribution

G. R. AL-Dayian, A. A. EL-Helbawy, R. M. Refaey & S. M. Behairy · Journal of Advances in Mathematics and Computer Science · 2021

Accelerated life testing or partially accelerated life tests is very important in life testing experiments because it saves time and cost. Partially accelerated life tests are used when the data obtained from accelerated life tests cannot be extrapolated to usual conditions. This...
