Supporting Information

Results Log Output

Select the box to output results to Results Log (in addition to that specified in Output Results).

Calculate

Power	Compute power for specified sample size.
Sample Size	Compute sample size for proposed power.

Test Specification

1st Group Rate	Value of rate for the 1st sample.
2nd Group Rate(s)	Value of rate for the 2nd sample. Support inputting multiple 2nd Group Rate.
Alpha	Probability of rejecting the null hypothesis when it is true.
Hypothetical Power(s)	Specify space-separated list of hypothetical power(s). Available when Calculate = Sample Size.
Hypothetical Sample Size(s)	Specify space-separated list of hypothetical sample size(s). Available when Calculate = Power.
Alternative Hypothesis	Perform a one- or two-sided test: Not Equal Indicates that the two-tail Poisson test is used. Less Than Indicates that the lower-tail Poisson test is used. Greater Than Indicates that the upper-tail Poisson test is used.

Exposure

Enter a value to divide the sample rate of occurrence into a more useful form.

Power Curve

Select to output power curves with assumption. The power curve plots every combination of power v.s. the 2nd Group Rate. Power curves are helpful for determining the appropriate sample size or power for the test.

Output Results

Determine where to create the output report worksheet. For more information, see Analysis Report Sheets.
