Hi,
My apologies for the naive question!
I have three overlapping sets and I want to find the probability of finding
a larger/greater intersection for 'A intersect B intersect C' (in the
example below, I want to find the probability of finding more than 135
elements that are common in sets A, B & C). For a two set problem, I guess
I would do a Fisher or chi-square test. Here is what I have attempted so
far:
#################
### Prepare a 3 way contingency table:
mytable <- array(c(135,116,385,6256,
48,97,274,9555),
dim = c(2,2,2),
dimnames = list(
Is_C = c('Yes','No'),
Is_B = c('Yes','No'),
Is_A = c('Yes','No')))
## test
mantelhaen.test(myrabbit, exact = TRUE, alternative = "greater")
###################### end code
Is this the right test (alongwith the current parameters) to determine what
I want or is there a more appropriate test for this?
many thanks!!
