A new inverse Weibull distribution : properties, classical and Bayesian estimation with applications

Abstract EN

This article proposes a new extension of the inverse Weibull distribution called, logarithmic transformed inverse Weibull distribution which can provide better fits than some of its well-known extensions.

The proposed distribution contains inverse Weibull, inverse Rayleigh, inverse exponential, logarithmic transformed inverse Rayleigh and logarithmic transformed inverse exponential distributions as special sub-models.

Our main focus is to derive some of its mathematical properties along with the estimation of its unknown parameters using frequentist and Bayesian estimation methods.

We compare the performances of the proposed estimators using extensive numerical simulations for both small and large samples.

The importance and potentiality of this distribution is analyzed via two real data sets
