Abstract

A two-parameter weighted inverse Lindley (TWIL) distribution, of which the inverse Lindley (IL) distribution
is a particular case, has been introduced. It’s properties such as survival function, hazard function, moments
and other associated measures are obtained. Moreover, parameter estimations of the new distribution by the
maximum likelihood estimation (MLE) and the bias-corrected maximum likelihood estimation (CMLE) are
also provided. Simulation results and applications to two data sets show that the new distribution outperforms
other extensions of the Lindley distribution.
