I have a monthly trend data (from Jan 2009 to Dec 2013, 5 years data reported as rates per 1000 each month) and I need to check for significance using PROC ARIMA. I DO NOT WANT FUTURE TRENDS OR FORECAST but I just need to check if there is a significant trend in the rates using PROC ARIMA. What sas codes/ command do I need to run? Any help with this is appreciated. I am attaching the excel data.
