Interesting.  Assuming you are right, I wonder if that is explicitly 
documented somewhere or if you are just supposed to figure it out 
based on your statistical understanding of the commands 
involved?  The postestimation help often just sends you to the 
generic link for a command - it would be helpful, I think, if little 
quirks like this were explicitly documented.  I've found a couple of 
instances where just typing "mfx" did not work, but there was 
apparently no documentation on what options needed to be 
specified.  But perhaps that helps to make sure that people only use 
a command if they really understand it!
