Linking Medical Expenditure Panel Survey to the National Health Interview Survey: Weighting and Estimation |
Description: |
|
This report presents the results of an investigation on the need for weighting adjustments for analysis and estimation when MEPS is linked with the NHIS full, sample adult or sample child files. The focus of the analysis is the MEPS full year (FY) file with variables transferred from the NHIS. For the analysis, the MEPS 2007 FY file is linked with the NHIS 2005 and 2006 files and the MEPS weights are adjusted for non-linkage. The estimates produced with adjusted and unadjusted weights are then compared to assess the impact of an adjustment of MEPS weight for non-linkage. The analysis shows that when MEPS is linked with the NHIS full file the impact of a weighting adjustment is negligible, but when linking with the NHIS sample adult or sample child file the impacts on many estimates are significant and a weighting adjustment for non-linkage is strongly recommended. |
