Seasonality Correction

Description:

Removes the seasonality from the selected time series. This metanode selects one time series column, optionally one datetime column, and an interval lag. Then it performs x(t) – x(t-interval lag) to correct the seasonality. Note: It does not find automatically the optimal interval lag. The interval lag has to be supplied by the user. (Optimal Interval Lag can be found via the linear correlation node, by knowledge, or by some specific formulas).

Contained nodes:

Lag Column:
Copies column values from preceding rows into the current row.
Java Snippet (simple):
Calculates a new column based on java code snippets.
