Hi All,
My apologies if this is a totally newbie question.
I want to calculate the probability that a particular set of genes is picked
repeatedly for 3 samplings. For example, if from a total of 'N' genes, I pick
'A' number of genes in the first pick, 'B' number of genes in the second pick,
and 'C' number of genes in the third pick, I would want to calculate p(n) where
n = (A intersection B intersection C).
Would fisher exact test be the correct method to evaluate the probability? And
if so how can I frame the 3x3 (?) contingency table? I can find numerous
examples of 2x2 tables, but none for 3x3. Any guidance would be appreciated.
many thanks.
