This study presents a new three-parameter beta distribution defined on the unit interval, which can have increasing, decreasing, left-skewed, right-skewed, approximately symmetric, bathtub, and upside-down bathtub shaped densities, U, hazard rates. model define well-known distributions with various parameters supports, such as Kumaraswamy, exponential, exponentiated uniform, generalized of firs...

The standard omega distribution is defined on the unit interval so that it a probabilistic model for observations in rates and percentages. It is, fact, form of exponentiated half logistic distribution. In this work, we first give detailed shape analysis from which observe another flexible beta-like We can be J-shaped, reverse U-shaped, unimodal show left right skewness according to values its ...

A copula is a useful tool for constructing bivariate and/or multivariate distributions. In this article, we consider a new modified class of (Farlie-GumbelMorgenstern) FGM bivariate copula for constructing several different bivariate Kumaraswamy type copulas and discuss their structural properties, including dependence structures. It is established that construction of bivariate distributions b...
