Sample Weights and Variance Estimation Clause Samples

Sample Weights and Variance Estimation. In the HC-018 file, a weight variable is provided for estimation purposes. Procedures and considerations associated with the construction and interpretation of person estimates using this and other variables are discussed below. In order to produce annual health care estimates for calendar year 1997 based on the full MEPS sample, data will also need to be pooled across the first two MEPS national samples. More specifically, full calendar year 1997 data collected in Rounds 3 through 5 for the MEPS Panel 1 sample are pooled with data from the first three rounds of data collection for the MEPS Panel 2 sample (for details, see H-020, Survey Sample Information, Section 3.0). Overall, the full 1997 MEPS household sample will consist of approximately 13,000 reporting units which include 32,636 individuals that completed the full series of MEPS interviews for their entire period of eligibility, providing the necessary information to produce national use and expenditure estimates for calendar year 1997. Panel 1 Conditioned on response to Rounds 1-3 of the Panel 1 MEPS, of 21,696 key and inscope individuals eligible for data collection in 1997, 19,622 (90.44 percent) provided data for their entire period of eligibility. Consequently, after factoring in the impact of survey attrition, the overall Panel 1 MEPS person level response rate for deriving annual estimates was 63.5 percent (.702 x .9044). Of these full year respondents for calendar year 1997, 19,407 were in scope on December 31, 1997. Conditioned on response to Round 1 of the Panel 2 MEPS, of 14, 644 key and inscope individuals eligible for data collection in 1997, 13,014 (88.87 percent) provided data for their entire period of eligibility. Consequently, after factoring in the impact of survey attrition, the overall Panel 2 MEPS person level response rate for deriving annual estimates was 69.2 percent (.779 x .8887). Of these full year respondents for calendar year 1997, 12,819 were in scope on December 31, 1997.
Sample Weights and Variance Estimation. In the database “MEPS HC-028: 1998 Full Year Population Characteristics,” weight variables are provided for estimation purposes. Procedures and considerations associated with the construction and interpretation of person and family-level estimates using these and other variables are discussed below. In order to produce annual health care estimates for calendar year 1998 based on the full MEPS sample, data will also need to be pooled across the second and third MEPS national samples. More specifically, full calendar year 1998 data collected in Rounds 3 through 5 for the MEPS Panel 2 sample are pooled with data from the first three rounds of data collection for the MEPS Panel 3 sample (the general approach is illustrated below—the anomaly of having the reference periods of some RUs in Panel 3, Round 2 extend into 1999 has been ignored here for purposes of clarity). Overall, the full 1998 MEPS household sample consists of approximately 9,023 reporting units (where student Rus are linked to parent RUs for this count) which include 22,953 individuals that completed the full series of MEPS interviews for their entire period of eligibility, providing the necessary information to produce national use estimates for calendar year 1998. 1999 Jan Jan Dec Round 1 Round 2 Round 3 Round 4 Round 5 Panel 3 1998-99 Jan Panel 2 1997-98 Conditioned on response to Rounds 1-3 of the Panel 2 MEPS, of 13,067 key and inscope individuals eligible for data collection in 1998, 12,260 (93.82 percent) provided data for their entire period of eligibility. Consequently, after factoring in the impact of survey attrition, the overall Panel 2 MEPS person-level response rate for deriving annual estimates was 64.95 percent (.6923 x .9382). Of these full year respondents for calendar year 1998, 12,086 were in scope on December 31, 1998. Conditioned on response to Round 1 of the Panel 3 MEPS, of 11,379 key and inscope individuals eligible for data collection in 1998, 10,693 (93.97 percent) provided data for their entire period of eligibility. Consequently, after factoring in the impact of survey attrition, the overall Panel 3 MEPS person-level response rate for deriving annual estimates was 70.76 percent (.753 x .9397). Of these full year respondents for calendar year 1998, 10,544 were in scope on December 31, 1998.
Sample Weights and Variance Estimation. In the dataset MEPS HC-189: 2016 Food Security Data File, a weight variable is provided for generating MEPS estimates of totals, means, percentages, and rates for families in the civilian noninstitutionalized population. Procedures and considerations associated with the construction and interpretation of family estimates using these and other variables are discussed below.
