NHANES III  Series 11, No. 7A, June 2001 Multiple Imputation (Updated August, 2004)

Multiple imputation is a statistical technique in which missing data are replaced by several sets of plausible, alternative simulated values. The multiple imputations distributed on this release provide
an improved method for handling missing values in many analyses of NHANES III data. These files are intended as a companion to--not a replacement for--other NHANES III public-use data sets.  National estimates from the NHANES III Multiply Imputed Data Set may differ from those obtained from Series 11, No. 1A (DHHS, 1997) and No. 2A (DHHS, 1998) files. Users of the NHANES III Multiply Imputed Data Set are advised to consult the detailed analytic guidelines in the documents provided in this release.
