An alternative distribution to Weibull for modeling the wind speed data: Inverse Weibull distribution
Akgül, Fatma Gül; Şenoğlu, Birdal; Arslan, Talha (Pergamon-Elsevier Science Ltd, 2016)Weibull distribution is widely used for modeling the wind speed data in literature. However, in real life, the wind speed data may not always be modeled by using the Weibull distribution. In other words, it may not represent ... -
Classical and Bayesian estimation of multicomponent stress–strength reliability for exponentiated Pareto distribution
Akgül, Fatma Gül (Springer Science and Business Media Deutschland GmbH, 2021)This study deals with the classical and Bayesian estimation of reliability in a multicomponent stress–strength model by assuming that both stress and strength variables follow exponentiated Pareto distribution. First, the ... -
