Table 1.
Comparison of the power functions under various hypotheses between the Poisson-based test ZPOIS and the weighted-least-squares based test ZWLS for two overlapping regions over disjoint time intervals, Region 1 (1980–1989) vs Region 2 (1990–1999). APC1 and APC2 are the annual percent changes in Regions 1 and 2, respectively.
