Hello I have two sets of integers eg
S1 = (25,14,32,45) and S2 = (26,12,31,48)
I want to define an operation similar to the variance that give me how
similar both sets are, for example in the above example for both sets
the results I have to get need to be similar because both sets are
similar.
The problem with the variance is this
S1 = (25,1,1,1) and S2 = (1,1,25,1) these two sets have the same
variance but they are completly different. What mathematical operation
can I use to do what I am looking for.
Thanks a lot in advance.
