Surveys often calculate weights to compensate for unit nonresponse. But what about item nonresponse? If different variables are missing from different cases, it seems to me the optimal set of weights would depend on the particular combination of variables being analyzed. Is there any systematic way to deal with this? The surveyor can offer different weights for different analyses, but the number of possibilities quickly become unwieldy.
