Influential Cases in Multilevel Modeling

The content below supports our research note Influential Cases in Multilevel Modeling (American Sociological Review, February 2010 issue).


  • Alexander Schmidt and Katja Möhring programmed the STATA ado mltcooksd which gives Cook's D and DFBETAs for second level units in mixed models. The ado is part of the post-estimation package multilevel tools (mlt) which can be downloaded here http://www.alexanderwschmidt.de/multileveltools.html . The mlt-package contains also programs for multilevel post-estimation in STATA, e.g. mltrsq which calculates the R-squared values for each level.
  • Rense Nieuwenhuis translated the MlwiN macro into the R package INFLUENCE.me.  He also wrote a supporting manual and presented the package during the 2009 UseR! conference in Rennes (France) . The package, manual, and presentation slides can be found by clicking on the INFLUENCE.me logo below:
