Stata Stored Results
Stata commands internally compute intermediary and final values. These can be useful for programming, so they are exposed as stored results.
R Class
The r() class stores results from general syntax commands. As an example:
count if EXPR local total=r(N)
Try return list, all to see all stored results available in the r() class. Leaving off the all option hides some results.
E Class
The e() class stores results from estimations.
Try ereturn list, all to see all stored results available in the e() class. Leaving off the all option hides some results.
S Class
The s() class stores results from parsing commands.
Try sreturn list to see all stored results available in the s() class.
N Class
The n() class stores results that don't belong in any of the r(), e(), or s() classes.
C Class
Not actually a class for stored results: see System Parameters.
