Thanks for your suggestion. I have run through a number of different
combinations of listing the duplicates, but I suspect that there are
duplicates that I can identify when limiting to certain variables but
that I do not obtain when including all variables due to data entry
errors. That's why it would be so great to have something that says
these are duplicate groups based on var x, var, and var z, and here is
the total number of variables that differ between the duplicate
observation.
Best,
Alison
