Generalized Weighted Weibull Distribution

The new class of weighted exponential (we) distributions obtained by gupta and kundu [14] by applying azzalini’s method to the exponential distribution. kharazmi et al. extended the we distribution to the generalized weighted exponential (gwe) distribution. in this study, we generalize the weibull distribution to a new class referred to as the generalized weighted weibull (gww) distribution with one scale parameter and two shape parameters. the gww model is constructed in a way that is similar to the way in which the gwe is constructed. it is investigated that the new model has increasing, decreasing and upside-down bathtub shaped hazard.
