(Need not be real, just realistic.)

I want to eliminate all the observations for a court case except for the observation that has the highest charge (homicide, robbery, etc.) I have 12 dummy variables that capture charges and used the duplicates command to get unique ids for each court case number. Is there a way to write a program that eliminates or keeps duplicates based on criteria you give it (Example, homicidedummy==1) and stops once all but one observation are eliminated? > Thanks. > > > * > * For searches and help try: > * http://www.stata.com/help.cgi?search > * http://www.stata.com/support/faqs/resources/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/faqs/resources/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/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
