New Statistical Approaches for Modeling the COVID‐19 Data Set: A Case Study in the Medical Sector

Statistical distributions have great applicability for modeling data in almost every applied sector. Among the available classical distributions, the inverse Weibull distribution has received considerable attention. In the practice of distribution theory, numerous methods have been studied and suggested/introduced to increase the flexibility level of the traditional probability distributions. In this paper, we implement different distribution methods to obtain five new different versions of the inverse Weibull model. The new modifications of the inverse Weibull model are called the logarithm transformed‐inverse Weibull, a flexible reduced logarithmic‐inverse Weibull, the weighted TX‐inverse Weibull, a new generalized‐inverse Weibull, and the alpha power transformed extended‐inverse Weibull distributions. To illustrate the flexibility and applicability of the new modifications of the inverse Weibull model, a biomedical…
