The RemoveBelowValue function is useful when the underlying data is known to contain data spikes which are irrelevant or invalid, and should be removed. 

Usage example

An Ad-tech company monitors the cost of several advertising campaigns. Occasionally, a bug is introduced in the data collection process, which results in a huge outlier: 


This spike, however, does not reflect a valid value, and should be removed. By applying the RemoveAboveValue function (specifying a threshold of 1000) the spike can be removed from the time series, and the normal pattern is clearly evident: 



Note: the RemoveBelowValue function can be used when the invalid samples are not spikes, but drops.
