title: "auto.arima" in SAS?
body: <p>I used to run arima model in R using "auto.arima" to identify the best arima model that fits the data. Even without it, it's easy in R to write a function to perform similar task. However, I have googled for the past few days, and I can't find a similar procedure in SAS. Does anyone know if there is a "auto.arima" in SAS? Or do I have to write one by myself? Thank you!</p>
  
  <p>Edit:
  After days of searching online, the closest one that I can find is Automatic Model Selection in time series forecasting package. However, that function is the one using GUI, and still one has to manually select all the different models to test. Does anyone know a command line procedure or package to do this? Thank you. </p>
