  A generalization of a distribution increases the flexibility particularly in
studying of a phenomenon and its properties. Many generalizations of continuous
univariate distributions are available in literature. In this study, an
investigation is conducted on a distribution and its generalization. Several
available generalizations of the distribution are reviewed and recent trends in
the construction of generalized classes with a generalized mixing parameter are
discussed. To check the suitability and comparability, real data set have been
used.
