MMERGE: Stata module: Safer and easier to use variant of merge


  • Jeroen Weesie

    () (Utrecht University)


mmerge is an extension of merge that automatically sorts the master and slave data sets, allows selection of variables, and provides more readable output describing the result of a merge. This version (2.5.0) is an update of that published in STB-53 for the latest revision of Stata version 7, which allows an unlimited number of match variables. The STB-53 version of mmerge should be used by Stata 6 users.
