Abstract:
|
Nonresponse in surveys can lead to potential bias of estimates. A strategy to address potential nonresponse bias is to carry out weighting adjustments to reduce nonresponse bias in the survey estimates. Auxiliary variables available for all sample persons are used in constructing nonresponse adjusted weights. With the sample for the MEPS being drawn from respondents to the National Health Interview Survey (NHIS), variables from the NHIS sampling frame are available on both MEPS respondents and nonrespondents. In this study, we compare the characteristics of MEPS respondents and nonrespondents by covariates, and then we examine the correlation between the covariates and selected survey variables. In addition, we assess the correlation between the nonresponse adjusted weights and various survey variables as a measure of the relationship between response propensities and survey variables.
