In fact, the current manual entry for heckman uses the more intuitive “nonselection hazard" instead of “inverse Mills", primarily because the latter has so many variations in the literature . Heckman's f(Zg)/F(Zg) corresponds to Greene's expression (I'm going to change Greene's notation slightly to match the Heckman model).

Within Stata, heckman can be used to estimate the sample selection model, and treatreg can be used to

30 Sep 2009 I am sorry for my unclear expression. In the thread n2.nabble.com/st-Re-Stata-Heckman-and-Mills-ratio-tt3707672.html#a3707672, Kit refered to "you can always create an r^2 I know the result of -heckman- is equal to the result of calculation manually in which first do -probit- then -reg- with mill.
Please note first of all that this is a double-posting of a question on statalist from the 17.1.2016 which as of now has not received any answer. I guess that its all right to double-post now because of what i read here (1). I am Heckman-regressing the effect of wealth on charitable donations heckman givings wealth
