Non-Response and Weighting Issues with the NHANES-CMS Linked Data

Purpose

This module provides information on linkage non-response and weighting the NHANES-CMS linked data.

Task 1: Survey Weights and the NHANES-CMS linked data

The survey weights in NHANES adjust for oversampling of specific subgroups and differential non-response, and are post-stratified to population totals for specific population domains to enable calculation of nationally representative estimates. Details on the NHANES sample design can be found in the continuous NHANES tutorial.  Whether and how to adjust these weights for linked data files that have incomplete linkage due to linkage ineligibility and non-matches is currently being investigated. 

• Key concepts of linkage non-response with NHANES–CMS linked data
• Key Concepts about weighting linked data
