In n:n coarsened exact matching, is there ever a situation where it makes
more sense to exclude study members and their respective control members
that have extremely large weights? For example, 500 study members match to
just 25 control members. Might it be better to exclude both study and
control members rather than introduce such large weights and variance to
the rest of the study population?
Thanks,
