  • Order of differencing. Can be 1 or 2.
  • The shift before differencing. Value of 1 equals to discrete differencing. You can use higher values to compute the difference between now and this many steps ahead.
  • Invert the differencing direction.
  • Select the series to difference.

To integrate the differences back into the original series (e.g. the forecasts), use the Moving Transform widget.
