NHANES data files are available for download from the website as SAS transport files (.XPT). To use these files you need to create a directory to save them, download the data files and documentation, and then extract and save as datasets.
You will create a directory to save your data files, documentation, and extracted SAS datasets. This will help keep your transport files and datasets organized.
You need the data files to create your analytic dataset, and you need the documentation for reference as you continue your analysis.
After downloading the SAS transport files, you will need to extract them as SAS datasets. Transport files are not usable without completing this task.
