I would be marginally concerned whether -mrate- takes care of the
complex sampling design. It's not in the publicly available through
-findit-, so I cannot check. I am also not quite sure if cluster level
estimates of mortality would make a lot of sense, either... just not
convinced enough for my limited survey statistics background.
