Figure 2

Comparison between Rodriguez-Brito's method and z test method. The x-axis and y-axis are occurrence rate P A and P B of two samples A and B. The 4 plots are made with different combination of sample size N A and N B as indicated in each plot. Red lines and green lines are calculated with Rodriguez-Brito's method and z test method respectively. Difference of A and B outside the area enclosed by a pair of red (or green) lines is statistically significant at 0.95 confidence level. This figure shows that when P A and P B become big enough (such as >0.001), a very small difference between them will be counted as significant.
