Guten morgen.(means ‘Good mornong’ in Deutsch)
Recently I read a paper entitled "Circulating Tumor DNA Mutation Profiling by Targeted Next Generation Sequencing Provides Guidance for Personalized Treatments in Multiple Cancer Types", the Dunn’s multiple comparisons test appeared in Figure 3 of that paper. When I search on Google, it is one of statistics, but I do not know statistics.
I know p <0.05 that it means "to reject the null hypothesis when p <0.05", but for what is it a test, what is the multiple comparison and the Dunn’s test I do not know.
1. What is Dunn’s test and what is test for blackening?
2. What is the multiple comparison?
3. Is Dunn’s multiple comparison test proceeding with multiple comparisons using Dunn’s test?
PS: Are Dunn’s test and dunnett test the different tests?
