The lag option L in this node is useful for time series prediction. If the rows are sorted in time increasing order, to apply a lag L to the selected column means to place L-1 past values of the column and the current value of the column on one row.The data table can then be used for time series prediction.
The lag interval option I (periodicity or seasonality) in this node is useful to compare values from the past to the current values. Again if the rows are sorted in time increasing order, to apply a lag interval I means to set aside on the same row the current value and the value occurring I steps before.
L and I can be combined to obtain L-1 copies of the selected column, each one shifted I, 2*I, 3*I, ... (L-1)*I steps backwards.
