Abstract :In this study, we introduce the five-parameter doubly-truncated exponentiated inverse Weibull distribution, where the truncation points are known, and consider its basic properties. Formulas for moment generating function, characteristic function, mean, variance and kurtosis of the distribution are derived. Estimates of parameters are obtained using traditional estimation methods; maximum likelihood, least squares and weighted least squares. Furthermore, in order to give a lower bound for the standard errors of estimates of parameters, a Fisher information matrix is provided. Finally, a Monte-Carlo simulation study is designed and conducted to evaluate the performances of obtained estimators of parameters.
Keywords : Doubly truncated exponentiated inverse Weibull distribution, Maximum likelihood method, Fisher information matrix
