Most of real time series include outliers. They can distort seasonality and trend estimations. The X11 method enables the user to reduce outliers influence by excluding the values that lie outside the specified range or by converting these values. Range width is set by the lower and the upper sigma limits. The lower sigma limit is determined by the IMsCensus2Transform.SigmaLower property.

The X11 method is supported only in Windows.
