Thank you Martin. Your code -loc ap5 = r(p5)- after -sum a, detail- works fine. Also, I really appreciate your careful looking at my code and finding about typos In fact, I got an error from -r(var)- exactly like you just told me. Well, I made all the typos here because I did not copy my code exactly from my program. I try to simplify and focus on my problem. Also, thank you Marrten for your suggestion. I will try out your suggestion next. However, Martin, I have a few questions for you, please. Your answer would help educate me about Stata programming. 1) For the 2 ways of coding, which one is faster in terms of simulating time. Also, for the first way, -r(p5)- has a specific reference to the 5th percentile from the -sum, detail- command, right? When I look at -r(r1)-, how and what would this refer to? 1st way: sum a, detail loc ap5 = r(p5) 2nd way: _pctile a, p(5) loc ap5 = r(r1) 2) I have tried to run your suggested program (copy and paste it in the do and run). I got an error saying class system failure class system failure class system failure class system failure class system failure class system failure --more-- I did -set trace on- and see a lot of red characters in many places. Also the -trace- output seems very long. I am not sure I should post it here. What would be the problem here?
