One of the biggest mistake of my(our) academic life was not even try to publish my research . So after 2 years since this work has done,i'm uploading our work here .This paper was writen in septembar 2017 . There are some work had done with the same topic in last 2 years though our conclution might be different from others.
The main objective of uploading this work after 2 years is to help other people who are thinking to do some work with ARIMA model .
