Abstract :
In this paper, a new discrete distribution is studied based on geometric
odds ratio. This new distribution has three parameters and can be a unimodal or a
bimodal discrete distribution. Some important distributional properties are studied.
For example, moments, the behaviour of the hazard rate function, stochastic orders,
mixing processes, infinite divisibility, Rényi and Shannon entropies and the distributions
of order statistics are investigated. We will see that the hazard rate function
of the new discrete distribution can be monotonically increasing and decreasing and
bathtub-shaped. The parameters of the distribution are estimated by the maximum
likelihood method, and a real data set is analyzed in order to show the effectiveness of
the model.
