  A generalization of the generalized inverse Weibull distribution so-called
transmuted generalized inverse Weibull dis- tribution is proposed and studied.
We will use the quadratic rank transmutation map (QRTM) in order to generate a
flexible family of probability distributions taking generalized inverse Weibull
distribution as the base value distribution by introducing a new parameter that
would offer more distributional flexibility. Various structural properties
including explicit expressions for the mo- ments, quantiles, and moment
generating function of the new dis- tribution are derived.We proposed the
method of maximum likelihood for estimating the model parameters and obtain the
observed information matrix. A real data set are used to compare the exibility
of the transmuted version versus the generalized inverseWeibull distribution.
