Carlos - Yes - the only thing I'd like to add is that you can define a user specified model repository yourself using the GUI. But of course you will need to decide for yourself which independent series or events to include. If you have a lot of potential candidates for independent series, you may want to preprocess your data trying to identify significant series yourself. One way to go about this is to do a similarity analysis of input combined with a cluster analysis. Purpose would be to identify similar patterns in your input series beforehand.
