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.
Quite true. It isn't like Stata has a patent on the formula for
logistic regression. Of course hunting all the formulas down could
Besides, your argument is contradictory. If StataCorp
is using the same formulas as everybody else, then they
can be found in the open literature.
For what it is worth, the great Satan does put its algorithms
online. When prompted for username and password, enter "guest" in both places.
I imagine Stata is often using the same or equivalent formulas. The
SPSS stuff may be free, but for me at least, the Stata documentation
is infinitely clearer.
