I am performing an analysis comparing my data against an NHANES dataset.
I am interested in testing the difference in means between the two groups, stratified by two variables (gender and age).
My data is heavily right skewed, so I will need to use a non parametric approach.
However, my own data is not weighted, but NHANES's data is.
How best would I go about performing this comparison?
Would I still be able to use proc surveyfreq or proc surveymeans?
