Proc Forecast

parmis — Wed, 22 May 2019 14:19:19 GMT

Hello,

I'm forecasting sales for the next 36 months. There is a seasonality pattern in 12 months of data that I have but the variable is always within the range of 100,000 (It increases very slowly over time). I'm using addwinters method for the forecast, however my numbers are lower than what I expected. Is there any way to adjust the forecast and get a higher numbers?

proc forecast data=work.mydata interval=month

method=addwinters seasons=month lead=36 trend=2

out=work.test outfull outresid outest=est;

id date;

var sales;

run;

Thanks!
