Hello, I'm using an expo model to forecast a variable monthly for a year. The problem is I get the exact same number for every month. I figured If I change the trend number to 2 or 3 then I get different forecast numbers every month but the forecast wouldn't be accurate. I have a constant model with a very slow moving trend so I thought trend=1 would be the right choise. any suggestions on how to handle this issue?   proc forecast data=have interval=month lead=12 method=expo weight=0.2 trend=1 out=want outset=est; var price; id date; run; Thanks! ...

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!     ...

Hello, I'm trying to forecast a variable for the next 36 months. my actual data has  seasonality but it is constant at the same time. I was using the following method to forecast for 12 month and I was happy with the result, but when I expand my lead time to 36 the numbers increase for the second year. Is there a way to modify the code to make the forecast constant? (the variable amount is always in the range of 100000-110000)   proc esm data=have out=want lead=36; id date interval=month; forecast amount/ model=addwinters transform=log; run;   Thank you! ...
