Abstract
In this article, the phenomena that follow the models for dealing with numerical data, which take the form of time series, have been dealt with. This type of time series often suffers from the problem of zero inflation. which represents a problem that cannot be overlooked. so a set of methods and methods has been proposed to deal with this problem. and one of the most important models in this case is Poisson's zero-inflated model. It should be noted here that there is a set of methods that are used to estimate the parameters of the Poisson zero-amplified model. including the MLE method and the NLM method
