- PARAMETERS specifies that the test direction is non-directional, the
significance level uses the default 0.05 value, the total number of pairs is set to 2, the testing
values for proportions are set the 0.5 and 0.75, marginal test values are enabled, the correlation
between matched pairs is set to 0, and the estimation method is normal approximation.
- PLOT specifies that the two-dimensional Power estimation versus risk
difference chart will display in the output. The three-dimensional Power estimation versus
discordant proportions chart will also display in the output. The vertical and horizontal rotation
settings use their default values (10 degrees and 325 degrees respectively).
