"time series seasonal Data"

Viktor_Meyer

Hello,

i already did the instruction on how to set up the arima in rapidminer....
but is there a way to increase the weights of data from the last years ?
If i want to window the day 15. december 2010 then it should weight the data from the 15. of 2009 08 07 more than other data.
Is there a trick to do that ?

thanks
Viktor
