This paper examines the potential usefulness of the transmuted modified inverse Weibull distribution. The four-parameter model holds eleven lifetime distributions as special cases. Some theoretical properties of the transmuted modified inverse Weibull distribution are studied; which includes the quantile, median, entropy, mean deviations, mean, geometric mean and harmonic mean. The estimation is obtained by using the method of maximum likelihood. An application to real dataset is provided to show the better fit of the transmuted modified inverse Weibull distribution.
