Recent Developments in Distribution Theory: A Brief Survey and Some New Generalized Classes of distributions

Abstract: The generalization of the classical distributions is an old practice and has been considered as precious as many other practical problems in statistics. These generalizations started with the introduction of the additional location, scale or shape parameters. In the last couple of years, this branch of statistics has received a great deal of attention and quite a few new generalized class of distributions have been introduced. We present a brief survey of this branch and introduce several new families as well.

“…In the practice of big data sciences, particularly in statistical theory, there has be an increased interest in defining new statistical models or new families of statistical models to provide a better description of the problems under consideration; see [6,7]. For more details, we refer to [8]. Often, adding extra parameter(s) gives more flexibility to a class of distribution functions, improves the characteristics, and provides better fits to the real-life data than the other modified models.…”
