### Apply Filter Check Box

The Apply Filter check box allows you to construct the feature set independent of whether or not the filtering is applied to the data. Using this check box you can choose to remove outliers for example, but not filter the data.

Raw Info from Andy:

The filter set accomplishes basically two things nowadays...The first is that it removes outliers. Outliers are data that falls far away from the expected location. We have two kinds of outlier removal methods for the filtered set. The first is linear. In this case any points that are far away from a line fit through the data is thrown out. The second is polar. In this case any points far away from a circle fit through the data is thrown out.

Someone may want to remove outliers but not filter. That seems odd because this is a filter object, but that's how it is.

When we filter the data we basically just make it smoother. This constitutes moving the points around so that the sharp bumps/edges are rounded off. So that check box is just to turn on or off the smoothing.
