Preliminary tests of normality when comparing three independent samples
Artikel i vetenskaplig tidskrift, 2016
This paper uses simulation to explore the performance of a two-stage procedure where a preliminary Shapiro–Wilk test is used to choose between ANOVA and the Kruskal–Wallis test as three-sample location test. The results suggest that the two-stage procedure actually seems to be preferable when conducting such location tests.
