Usage example

A manufacturer wants to monitor the temperature of heavy machinery. The temperature sensor is not 100% reliable, and is known to occasionally drop to zero:

These drops, however, do not reflect valid measurements and should be removed. By applying the RemoveBelowValue function and specifying a threshold of 0.1, all invalid zero samples can be removed from the time-series: 

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