发帖数: 587 | 1 Assume G variables, each variable can be positive or negative
group A, a subgroup of G
group B, a subgroup of G
the same variable in A and B can have different values (both positive,
or negative, or one positive or one negative)
I wonder if there is a way to give a P value to how A and B overlap,
considering positive or negative (direction only).
All I can think about is to take their overlap, then calculate chisq
based on contingency table (positive/negative) of A and B.
Not sure if there are other ways, like concurrence rate, take the size of
G into consideration.
