Statistical Analysis of Non-Homogeneous Poisson Process Described as Weibull Process with an Application

This research deals with the non-homogenous Poisson process described as Weibull process. In order to estimate the rate of occurrence, maximum likelihood and least square methods have been used, in addition to the graphical method which investigates the suitability of the power low function of the data for the research and estimating the rate of occurrence.The practical application includes studying intervals between rainfall in two main weather forecasting stations of Nineva. Thus, the rate of rainfalls has been estimated by using the suggested statistical method in the research.
