Exponentiated Weibull Weibull Distribution: Statistical Properties and Applications

We introduce a new five-parameter model related to Weibull distribution, the so called. exponentiated Weibull Weibull (EWW) distribution.   It  incluides some new and earlier distributions. Fundamental properties are deduced. We deal with maximum likelihood (ML) method to obtain parameter estimators. The interest of the recommended distribution is confirmed through real data sets .
