    I think you need the series extension to do the things tom did there.

    Yes i installed Series extension. Problem is, no matter which operator I use, result table is still in form :

    ID;      Label;        Predicted Label;        Variables ........


    How to build model which can forecast bigger horizon than 1 ?  With result table that looks like:

    ID;      Predicted Label
    n+1          xyz
    n+2          xfka
    n+3          ....

    etc.

    With unknow variables for forecasted variables, just with learned model to catch Trend and seasonability during year ?

    Dont need to forecast exact values, only direction of further development.  :)

    Hi,

    just a short answer because i need to go:
    The trick is windowing. You create a table like this


    label  var1_n-1, var2_n-1, var2_n-1,

    then you can do it. Obviously the window can be longer than one and also contain more complex things.
