Dear @ScottF ,
As I posted in greater detail at < Autocorrelation and Seasonality in Time Series >, I am facing a somewhat comparable situation.
Notwithstanding, I could not install Python (or its libraries) on my PC. Therefore, I could not apply any suggestion similar to the one depicted in this post. So, I ask you if you might help me with a solution (in Knime, but without Python or R) to my problem, as stated in the forum (link above).
Thank you for any help.
B.R.,
Rogério.
