The functionality Clyde is looking for is provided by -mi set-. To delete specific imputations, for example, 1, 3, and 5, Clyde can type . mi set m -= (1 3 5) Clyde may also be interested in -mi set M- to delete imputations from the end. There is a section in -help mi set- describing these two features. -- Yulia ymarchenko@stata.com * * 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/
