Question on Odds ratio

#1
Hi,

I have a basic understanding of odds ratio. I can't figure out how to integrate the space S into my odds ratio equation.

For the following figure:
S has 23000 genes, (all genes)
A has 751 genes and (condition1)
B has 375 genes (condition2)



How do I calculate the OR for A ∩ B?

Thanks

I did not follow your example/problem at all. If possible please rephrase it or provide more information.


I would start by trying to put your data into a classification table (AKA, confusion matrix).
