This won't work this way. -missing()- just returns 0 or 1; it will not count missings across observations. You need to construct a variable that includes the counts. -egen- includes various functions that might help. Nick n.j.cox@durham.ac.uk Abu Camara I am doing some aggregation on some indicators by region and would like to have no aggregation for year if 1/3 of cases for particular year are missing. I tried the following command but did not get what I wanted. Any suggestion /help would be appreciated. Thanks in advance. ***--command----------. table country year [aweight=pop1] if year==1980 | year==1990 |year==2000 | year>=2004 & missing(year)>19, /// c(mean ger_pri_tot) format(%9.1f) row * * 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/
