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.
