Class TimeseriesFeatures

java.lang.Object

fact.statistics.TimeseriesFeatures

All Implemented Interfaces:

stream.Processor

public class TimeseriesFeatures
extends Object
implements stream.Processor

This processor calculates several features of the timerow in a given timewindow: - mean, std, skewness, kurtosis - median, mode, min, max, quantil 25%, quantil 75% - histogram (over all events) from the difference between the data voltages and the voltages after a moving average filter
