[R] Off topic - Combine results of two testing procedures
Hello list, I have a question not directly linked to R, I have googling during one day but did not find any satisfying answer. Perhaps some people of the list could give me some advices. Here is my problem, I compute a statistic which measure the link between three tables X (n,p), Y(p,m) and Z(n,q). I would like to conduct a test the hypothesis that X,Y and Z are linked. I have implemented two testing procedures (by monte-carlo permutation) which test: Ho: X,Y and Z are not linked vs. H1: at least X and Z are linked Ho: X,Y and Z are not linked vs. H2: at least X and Y are linked I would like to combine probabilites from these two tests in order to test Ho: X,Y and Z are not linked vs. H3: X ,Y and Z are linked I can not implement a direct permutation procedure to test Ho vs H3, and wonder if there is one way to deduce it from the two first testing procedures. Help and reference are welcome, Thanks in advance, Sincerely.
