Re: DZ

I see now DZ has been elevated to Luis A. Afonso's "subject pollution"
list!

All text-books say this

MY textbooks are counterexample to your statement. :-)
How many textbooks have you seen in your life time to make
your "All text-books say" statement?

But that's only a misdemeanor on Afonso's part.


Let be M a population (one dimensional case) parameter which I want to evaluate its location relative to M0

H0: M>M0______H1: M<=M0 (1)
H0: M<M0______H1: M>=M0 (2)
H0: M=M0______H1: M=/ M0 (3)

_____licas (Luis A. Afonso)

Never mind what all textbooks say. The important point is one of
the points made by ME, that it makes NO DIFFERENCE in the
proper execution of any of the tests above, if the Ho hypotheses
are stated as M = M0:

H0: M=M0______H1: M<=M0 (1a)
H0: M=M0______H1: M>=M0 (2a)
H0: M=M0______H1: M=/ M0 (3a)

Explain to us any DIFFERENCE in the execution of a hypothesis
test on (1) vs (1a); (2) vs (2a); or (3) vs (3a).

And stay with the same subject heading you started.
