Hi ,

 

I am trying to use proc X11 to forecast my sales. 

But i am facing a problem that there is a negative value in my time series(due to return on that particular month).

please suggest me if there is any solution in proc x11 to handle this situation or do i need to handle it other way arround?

 

Thanks in advance
