NHANES-CMS Linked Data Tutorial

Merge Feasibility File and NHANES Data

Purpose

This module provides instruction on how to merge the SAS-formatted datasets from the feasibility and NHANES data files created in the previous module, into a single analytic dataset.

Task 1: Merge Datasets

Once you have created the SAS-formatted feasibility and NHANES datasets you will then need to merge them by SEQN. For analytic purposes it is not recommended that you subset the data. In this task, both files are sorted, and then merged to create a new SAS dataset. SAS coding examples are included.
