Technical Notes on Nesting and Weight Variables

The design of the 2004 National Nursing Home Survey entailed multi-stage sampling, each stage involving sampling within a defined grouping or cluster. The current prescribed medications public-use file includes the nest variables of the sampling framework for use in statistical software that accounts for complex sample designs in the estimation of variances and standard errors. Proper adjustment of standard errors for stratified or clustered sampling provides the analyst with accurate significance tests.

The nest variables or sampling stages in the prescribed medications file are RSTRATA and FACNUM and are taken from the current resident file. The sampling weight which represents each observation's contribution in the estimation of the current resident population is SAMWT.

In the statistical software, SUDAAN, the analyst can use the design option WOR for sampling without replacement. When using SUDAAN for WOR, the variables for the TOTCNT statement in SUDAAN are POPFAC and NPOPRES. Below are the SUDAAN statements for the NEST and TOTCNT statements for the prescribed medications public-use file with WOR. The example uses the crosstab procedure to illustrate.

proc crosstab data=[filename] design=WOR nest strata facnum / missunit; totcnt popfac npopres weight samwt;
