Margin and Alpha

Defines the significance levels for the test.

**Difference**

(Available only for tests for risk difference.) Specifies the equivalence, superiority, or noninferiority margin. This margin, or delta, is the difference that has practical significance. For equivalence tests, the difference must be greater than zero.

**Ratio**

(Available only for tests for relative risk.) Specifies the equivalence, superiority, or noninferiority margin as a risk ratio. This margin, or delta, defines a risk ratio that has practical significance. The range of values is defined as (Ratio, 1/Ratio). For equivalence tests, the ratio must be different from 1.

**Alpha**

Specifies the significance level for the test.
