Table 2 False positive rate detected by the Improved RIDIT and MWW relative to nominal α = 0.05 using simulation under the null hypothesis. Three examples of distributions under H0 were used according to the level frequency profiles in Fig. 1

From: Improved RIDIT statistic approach provides more intuitive and informative interpretation of EQ-5D data
