Time is one of the major factors in natural events whose accurate prediction has always been considered by human. Sudden and unexpected occurrence of some of such events, especially those with great range of changes, have brought humans many problems. Today, it is tried to predict the return period of events using mathematical equations and statistical relationships, especially statistical distributions.
The main goal of this paper is precise prediction of events with relatively great range of changes. In this regard, common distribution models have been exploited in a way that this goal can be achieved. This research is based on statistical relationships, and it has been tried to estimate the quantitative values of events and their time of occurrence.
