Abstract
Here, the Poisson compound of quasi Suja distribution called quasi Poisson-Suja distribution is proposed. A general expression for the rth factorial moment of this distribution has been obtained to derive its first four moments about origin and the central moments. The descriptive properties based on moments have been discussed. The proposed distribution is unimodal having increasing hazard rate and over-dispersed. Some interesting and useful statistical properties including unimodality and increasing hazard rate have been discussed. A simulation study has been done to test the performance of maximum likelihood estimates of parameters. Finally, the goodness of fit of the distribution discussed with two discrete datasets, the first from biological sciences and the second from thunderstorms and compared with the goodness of fit of Poisson- Lindley distribution, Poisson-Akash distribution, Poisson-Suja distribution, quasi Poisson-Lindley distribution and quasi Poisson-Akash distribution. The result shows that the proposed distribution provides greater flexibility in modeling real over-dispersed count data over the considered distributions.
