Cycle 6 Variance Estimation Each of the pdf files below provides programs and output in SAS, SUDAAN, STATA, and WesVar for nine examples of variance estimation. These examples are intended to cover many of the common types of variance estimation you may do in your analyses. If you have any questions about any of these examples, please e-mail the NSFG staff at nsfg@cdc.gov.
