I have written proc sumamry code for getting descriptive statistics, my resultant dataset consists some missing values(numerica variables) and i replaced them with zeros...........by using options missing='0' before the proc statement.
So could you please let me know whether the method which i am following is giving expected results ot not?
Can you describe your situation a bit more? Where are you seeing missing values (for class variables or summary statistics)? What PROC summary code did you submit?
Keep in mind: the missing option does not replace missing values, it just changes how they are displayed.
SAS help states that "PROC MEANS excludes missing values for the analysis variables before calculating statistics". I believe that it is also true for proc SUMMARY. So, if you need that your missing values of analysis variables have been treated as zeroes it is necessary to replace them with zeroes in a separate datastep before proc SUMMARY.
