Abstract:
|
The estimates of the influenza vaccination rates were produced for each county by population subgroup from the Behavioral Risk Factor Surveillance System. An expedient small-area estimation method was used. This evaluation focuses on the agreement of the estimates with estimates known to be more reliable from various angles. First, the county-level estimates were aggregated based on population distribution to generate state estimates, which were compared with composite state estimates and the survey-weighted hierarchical Bayes state estimates. Second, random samples of counties were selected, and the estimates in a selected county and its surrounding counties were aggregated to generate neighboring area estimates, which were compared with composite estimates for the areas. Third, design-based estimates were obtained in counties where the sample size was deemed large as a comparison.
