    Hi all,

    I'm new to data mining, so any help will be appreciated.

    I've created the Forecasting time series model following the online tutorial at, but I have problems interpreting the decision tree in the model viewer.

    On some nodes, the rule looks like: M200 Europe.Amount-2<67910,9375. My first question is, what does "-2" mean? It certainly is not "subtract 2" by amount. Then does it probably mean M200 Europe.Amount two months ago?
    Another question is, in the mining legends for these nodes, there are terms like: Amount(M200 Europe,-2) or Amount(R250 North America,-12). They look like functions but what is the second argument? Is it number of months?

    Please help. Thanks a lot!
