In case you are curious, this is how to properly set up the NHIS data that we use in class for teaching purposes. It took me some time to understand how to do it, and I am not even sure if this is the exact setting. The documentation is here as slides, or here as notes. I am not the only one who found it difficult to set up. The NHIS documentation itself helped a bit, but not as much as reading online.
