Iterations Using Moving Average

KNIME Analytics Platform

Hi
I am working on time series forecasting using Moving Average. I am not able to create iterations for different window length. I have created a table with different length but this values are considered as string datatype not as a int.

Hi,
You can use the String To Number node to convert strings to numbers.
Kind regards,
Alexander

 I tried that node but the problem is flow variables data type is not changed . For Example: I have window length 6,7,8 I have to use these 3 number in moving average flow variable but the problem is Window length in flow variable accept only single value not a multiple value another problem is it consider that 6,7,8  in Flow variable as  String [  ] .

Hi,
Then you have to loop over a table with your desired window lengths, e.g. using Table Row To Variable Loop Start. In each iteration you run the moving average with a different value for window length and in the end you can collect everything with the right loop end node.
Kind regards,
