Expanding the National Health Expenditure Accounts (NHEA) Technical Documentation - Chapter 9

We estimated prevalence and standard errors of calibrated disease groups from each multiple imputed (MI) dataset, and combined estimates from the 5 MI datasets using standard MI rules.  The 'final weight' was calculated as the product of the existing MCBS survey weight and the calculated 'selection' weight. The results across the years, 1999-2009, are shown in Table 9.
