As I mentioned before I had been treating repeated measures with multilevel models, given I don't typically have many panel measures. This and I don't think there is any moving averages to control for. Though, as I noted, I am slowing trying to pick up some time series knowledge. I am still a novice and the multivariate time series is beyond my current level, since I still need to master the univariate models.
What do you mean by ARDL in particular? Is this the process to determine how long a lag should be based on AR?
Oddly, I saw a printed chapter sitting in my closet on Saturday on forecasting using SAS, but it didn't say what book it was from, just Chapter 2? If Ii remember, I will try to look up the source tomorrow. You are lucky you couldn't open GG's links. I did and they were full of propaganda and evil. Just kidding, even worse for you (per your prior posts), most were VERY formula heavy.
