    Hi,

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

    I've created a Forecasting time seriese model following the tutorial: Lesson
    3: Building the Forecasting Scenario at
    http://msdn2.microsoft.com/en-us/library/ms169846.aspx.

    In the decision tree of the model viewer, some nodes have the rules like
    "M200 Europe.Amount-2 >= 67910,9375." My question is, what does "-2" mean? It
    doesn't look like minus 2 by amount, then does it perhaps mean M200
    Europe.Amount two months ago? Also in the mining legend for the leaf nodes,
    the term column has some values like "Amount(R250 North America,-12)." Does
    this also mean R250 North America.Amount 12 months ago?

    Please help. Thanks a lot!

  2. "M200 Europe.Amount-2 >= 67910,9375"
    It represents the value of the M200 Europe.Amount attribute two time slices
    ago.
    In the example, a time slice is one month so, yes, it means two months ago
