On a Generalized Lindley Distribution

Rasool Roozegar, Saralees Nadarajah


Nedjar and Zeghdoudi (2016) studied various properties of a distribution which they claim to have introduced. Here, we point out that the distribution is a particular case of at least two known distributions. Most of the properties derived by Nedjar and Zeghdoudi are already known. We also point out that most of the results presented by Nedjar and Zeghdoudi are either incorrect or not useful.
