"Konstantinos Pitsakis" <K.Pitsakis@uvt.nl> posted a question
concerning -sgmediation-  with panel data.

The -sgmediation- program is not very sophisticated and does not
analyze panel data correctly.  Regardless of whether data are xtset or
not, -sgmediation- runs OLS regression without clustering.  It should
be possible to compute indirect effects with panel data but
-sgmediation- is not the proper tool for this.

Regards,

Phil
