摘要:

Assuming a constant α, tables oftwere developed using the Šidák multiplicative inequality: when doinggdifferent contrasts the familywise rate of Type 1 errors, fwi ≤ 1 − (1 − α)g. Values oftare given that yield fwi = .01, .05, .10, or .20 for number of contrasts,g= 2(1)10, 15(5)50 and degrees of freedom,v= 2(1)30, 40, 60, 120, ∞. Thesetvalues are smaller than those in the previous Dunn (1961) tables, thus yielding slightly improved power.
