I am looking into using the Matching package for some multi-level analysis with multiply imputed datasets, and so far I have been unable to get a handle on how to appropriately deal with these issues when using genmatch() in the Matching library. Here are my basic questions: -Is the 'weights' option in genmatch the appropriate place for incorporating sample weights? -Is there a way to work with multiply imputed data sets other than manually running the analysis on each dataset and then averaging the results? -I am working with multi-level data that has respondents nested within neighborhoods. How would you suggest I account for this clustering in genmatch? Thanks!
