3. Simulation results
In the following 2 figures some results for a specific situation of five levels of the factor
and 5 observations within each sample are shown. The ratio of "true" standard deviations
( σ1 :σ2 :…:σ5 ) was given by 3:1…:1. In Figure 1 the empirical type I error rate was
compared to a nominal one of 0.05 for all 7 methods
