In this paper, a three parameters generalization of the power Lindley distribution is
introduced. This includes as special cases the power Lindley and Lindley distribution. The
new distribution exhibits decreasing, increasing and bathtub hazard rate depending on its
parameters. Several statistical properties of the distribution are explored. Then, a bivariate
version of the proposed distribution is derived. Finally, three real data applications illustrate
the performance of our proposed distribution.
