Abstract : In this paper, we propose a new distribution obtained by mixing gamma and geometric distributions. We discuss different shapes of the probability density function and the hazard rate functions. We study several statistical properties. The maximum likelihood estimation method is performed for estimating the parameters. We determine the observed information matrix and discuss inference. Illustrative three hydrologic data sets are given to show the flexibility and potentiality of the proposed distribution.

Keywords : Order statistics Geometric distribution Gamma distribution Record values Estimation
