Many distributions have been used as lifetime models. In this article, we propose a new threeparameter Weibull–Pareto distribution, which can produce the most important hazard rate shapes, namely, constant, increasing, decreasing, bathtub, and upsidedown bathtub. Various structural properties of the new distribution are derived including explicit expressions for the moments and incomplete momen...

Analyzing time to event data arises in a number of fields such as Biology and Engineering. A common feature this is that, the exact failure for all units may not be observable. Accordingly, several types censoring were presented. Progressive allows randomly removed before terminal point experiment. Marshall-Olkin bivariate lifetime distribution was first introduced 1967 using exponential distri...
