We introduce a four-parameter distribution, called odd
Burr power Lindley distribution, which extends the Lindley distribution and has
increasing, upside-down and bathtub shapes for the hazard rate function. Our
purpose is to provide a generalization that may be useful to still more complex
situations. It includes as special sub-models some well-known distributions
such as Lindley, power Lindley, odd log-logistic Lindley, among others. Several
statistical properties of the distribution are explored. A simulation study is
performed to assess the maximum likelihood estimations of introduced
distribution parameters in terms of bias and mean square error, estimated
average length and coverage probability.
