Arima Model Creation Help

pauliet987 — Wed, 21 Dec 2022 20:23:29 GMT

Hello,

I am trying to make an Arima Model to predict how many positive cases will occur the next week based on all previous number of labs performed in previous weeks Example:

Week_Start Labs_Performed Number_of_Positive_Cases

11/04/2018. 230 31

11/11/2018. 260 45

There is about 6 months worth of data but all put into a weekly format. How do I make an arima model to accomplish this. Thank you for any help you can give!

A great place to start is the Getting Started example for the ARIMA procedure in SAS/ETS software. Work your way through the example, but use your real data. When you get the FORECAST statement for making predictions, it sounds like you want to make a 1-step forecast for the next week:
forecast lead=1 interval=week id=week_start out=results;
