Kaiser Family Foundation ACA Eligibility Analysis: Technical Appendix C: Imputation of Offer of Employer-Sponsored Insurance
April 7, 2015
Source: Kaiser Family Foundation

To impute the presence of an offer of employer-sponsored insurance (ESI) for each person in the sample, we followed the broader methods of our Immigration Status Imputation (described in Technical Appendix B), tailored to this characteristic of survey respondent. This approach uses the Survey of Income and Program Participation (SIPP) to develop a model that predicts whether each individual in the microdata has an offer of ESI. Unlike the Immigration Status Imputation, this method does not control the model results to a second data source, since the source data set in this case (SIPP) can be thought of as the authoritative source for this statistic. Below we describe how we developed the regression model and applied it to the Current Population Survey. We also describe how the model may be applied to other data sets. The programming code, written using the statistical computing package R v.3.1.1, is available upon request for people interested in replicating this approach for their own analysis.
