RE: st: Standardized Response Mean. Does Stata calculate this?

[Nick Winter <nw53@cornell.edu>]

Given the name (ES-II), it sounds like an effect size of some sort.

That would suggest that it is NOT the t-test from the difference of 
means (that is the difference divided by the standard error of the 
difference), but rather the difference of means divided by the 
standard *deviation* of the difference.  That latter is derivable 
from the results of t-test; I don't know if anyone has packaged it.


I share Nick C's amusement, though.  I suppose as long as many 
asterisks are attached to the relevant number, people downstream will 
probably be satisfied.
