WebAug 27, 2015 · $\begingroup$ Actually, having two separate threshold values is exactly the same: the hysteresis method is based on applying two separate threshold values for the 'on' and 'off' events. If you observe the signals 'live' in a y/t viewer or plot, it is sometimes clearer to see only one threshold line (which changes with each event) instead of having two lines. WebA threshold of five compared with the current European Medicines Agency threshold of three gave a reduction of 25 % in false positive signals in return for a loss of 12 % in true signals detected early.
