Problem Set 3

Here is the final problem set, which covers weighting-based corrections for nonresponse and self-selection. To make things simpler, I have created an  .Rdata file which has a self-weighting subset of the November 2008 CPS. This was created by sampling the entire CPS file described in the problem set with probability proportional to the weights. The file is smaller--10,000 rows--and does not need to be weighted, which makes it easier to use with either glm or the quantile functions. The .Rdata file also includes the ANES Internet panel data and all categorical variables in both data frames have been made into factors (with appropriate labels).
