"Dots" are in Stata numeric missings. My code, like yours, presumes that r(mean) and r(sd) exist in memory as a result of some previous command, e.g. -summarize-. If that is not true then the result will be as you describe.

How could it be dealt with?

The opening and closing ticks should be different: `m' Note that in your example locals are unnecessary and just complicate the code: gen affiloui2=(affiloui - r(mean))/r(sd) Nick n.j.cox@durham.ac.uk saqlain raza I am in try to make a -local- with the following command: local m=r(mean) local sd=r(sd) Then I try to generate a variable. gen affiloui2=(affiloui - 'm')/'sd' but it gives me an error 'm' invalid name r(198); I have tried with double quotes but even then it is not working. How this problem can be solved? Is there any problem in making -local-? Note that affiloui is already a variable in the database. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
