Assume we have two kind of fridges A and B, and a function set F = {f1,f2...,fn} and each function has its corresponding weight
W = {w1,w2,...,wn}, I want test whether difference exist between A and B on cover the functions in F.

1 I know that without the weight, we could do it like this:
First create the 2*2 table
                              

     A               B
covered functions         a                c
uncover functions         b                d

Then use chi-square test.
But with the weight, what should I do.


2 How to test whether A covers more functions than B considering the weight.
