There is another answer, although you may not like it
much. In the case of many commands implemented by ados
you can look at the code. -viewsource- is one way to
do it. This isn't always easy when a calculation is
spread across several lines of code or several different
programs, but it does answer quite a lot of questions.
Your last comment has already been answered several times
over in this thread. Like it or not, StataCorp has invested
a vast amount in its documentation for sale and wholesale
duplication of the manuals for open access just is not
likely. We can all agree that it would be useful if it
were there, but it is not going to happen. That's my
guess, at least.
Besides, your argument is contradictory. If StataCorp
is using the same formulas as everybody else, then they
can be found in the open literature.
