Have two data sets with common variable. The teacher data set has several teachers per school. The school variable is a nominal variable that is unique to each school. So if there are 20 teachers in a school the school variable is repeated 20 times. The principal data file has one principal per school and I want to merge/match on school. There is one principal to each school and this file uses the same school variable to identify the school the principal is in. What I need to do is to match the principal data to every teacher in that school. So the file would look like: School teacher_var1 teacher_var2 principal_var1 123 23 45 56 123 25 44 56 123 21 43 56 123 56 55 56 331 21 22 51 331 21 29 51 331 26 21 51 Help please * * 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/
