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

Re: time series predicting the future price

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.  Smiley Happy

Re: time series predicting the future price

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.
