Yes, this is what so called sheaf coefficients where designed
to do, see: Heise, David R. (1972). Employing nominal
variables, induced variables, and block variables in path
analysis. Sociological Methods & Research, 1(2): 147--173.
These sheaf coefficients can be computed in Stata using the
-sheafcoef- package, which you can install by typing in
Stata: -ssc install sheafcoef-
Hope this helps,
