Abstract:

The objective of this paper is to show with what probability differences between numbers of observed events within a pair of time intervals may be ascribed to specified changes in rate of a periodic phenomenon. In the example given above it might be required to say with what probability the observed difference of 25 - 10 15 events might be ascribed to an actual rate change of 0, 5, 10, 12, etc., events per interval. Such measures are valid for the class of phenomena, such as human heart rate, for which magnitude of rate change is relatively unrelated to base rate Kaelbling, King, Achenbach, Branson, and Pasamanick 1960, Avner 1964.
