I have recently come across a problem that is clearly out of my level of background, so perhap someone can help:
I wish to determine if condition 1 is related to conditions 2,3,4 etc. its not clear to me just yet how many conditions will ultimately be involved. I would like to get a sense of how to treat this. for each condition the is either a true or false outcome.
let me give an example that may help: I wish to know if the proportion of instances of condition 1 being present is greater or lesser when condition 2 is also present, then if it is greater when cond 3 is present and so on. now that part i can handle. but i would also like to know if the proportion of cond 1 is greater when both conditions 2 and 3 are true, or both cond 3 and 4, or both 2 and 4, or even if three conditions are present (ie cond's 2, 3 and 5).
I would think this has been done often, i just need a push in the right direction.
