Trying to figure out how to model a categorical predictor in your regression?
Done this code a million times but can never remember the syntax for the class statement?
Want to generate exponentiated estimates and confidence intervals?
We'll give examples for binary, 3 levels, 4 levels, and stratified.

Short post today on how to use the MEAN function in SAS 9.4. Let's get started.
It seems like every time I need to calculate a mean variable in SAS, I find myself looking up which CALL functions deal with missing values in this way, and which in that way.
For example, blood pressure readings are often taken 3 times, and then we average those 3 readings together for a mean value. In some code I ran earlier this morning, I kept getting negative values in my "avg_bp" variable. What's up with that?
