I have lists of pair like so :
KHLM1800, (a,b,c) KHLM1900, (a,b,d) KHLM1840, (a,b,c,d) KHLM1845, (a,b,c) TCMB9001, (a,c) . . .
Naively it looks like KHLM and (a,b) have a strong relationship. (1800 and c ) and (40 , d) are some how related ( last one is seems to be weakly related).
Is there a way to quantify the relating parts to each other and the strengths of the relationship? By "way" I mean what type of algorithms deal with somewhat similar type of questions?
Title was the best I could come up with
