Re: [R] exact wilcox test and Bonferroni correction

using p.adjust. For the example above the p-bonferroni value was 1. The threshold p-value is 0.00625 (that is 0.05/8) Finally, because p-bonferroni 0.00625 can I conclude that for each item my samples are from the same distribution? I am a little bit confused thank you! netrunner -- View
