Hi, I don't know much about time series, but so hoping someone here does that can help. I'm trying to build a model in SAS that forecasts the home price increases by city. My data has year-month and home price (Y variable) for the last 12 years by city. I also have some other variables like home start-ups, days-on-market, unemployment rates, income, and many others... can I use all these as X-variables in a time series model.. if so how in SAS? Thanks..
