Proportion of Top-Ranked Tests Exceeding Dunn-Šidàk and Gamma Model Significance Thresholds.

The Dunn-Šidàk significance level (D-S alpha) is calculated in the traditional manner attempting to provide an experiment-wise significance level of 0.05. In an analogous fashion, the Gamma Model significance level (G alpha) is calculated using the simulated data, also attempting to generate an experiment-wise significance level of 0.05. Table 1 shows the results of a Monte Carlo simulation evaluating 13 models. Using the respective significance levels, the proportions of top-ranked tests exceeding the respective significance levels are presented.
