I never heard of Herman Rubi, but here is what
Professor Herman Rubin wrote on November 26, 2005.

http://www.math.yorku.ca/Who/Faculty/Monette/Ed-stat/0
241.html

"I have yet to see a classical approach which
considers the balance.  But if one assumes that the
decision maker is consistent, then it is an easy
result that action must consider a linear combination
of the probabilities of the resulting outcomes in the
various states of nature. Looked at otherwise, this
corresponds to minimizing the integral of some
consequence function with respect to some measure on
the states of nature. This is the behavioristic
Bayesian approach. But it is not the philosophical
one; only the product of loss and prior is even
considered by this. To take a simple example, suppose
one is testing
that the mean of a normal distribution is exactly
0. Then the probability of rejecting the null
hypothesis if it is true must be balanced against an
integral of the probability of accepting this
hypothesis over the non-zero values of the mean with
respect to some measure. It is not that hard to
proceed from this type of approach."

What is this business about "the probability of
accepting this (null) hypothesis"?

My comment

YES I made an error: the guy is Herman Rubin.
HOWEVER you called Prof. TIAZ when the ecat name is
TIAGO (de
Oliveiea) THEN you had 1 letter absent (O) and 1
wrong (Z by
G).Conclusion: YOU ARE WORSE THAN I AM.
BY THE WAY : why you don´t ask him if the Null
Hypotheses can be proved tue, then acceptable?
LET US KNOW WHAT HIS OPINION IS!!!!

Luis Amaral Aoso [the moderator destroyer]

The null hypothesis does not have to be proven to be true to be accepted.  Professor Rubin talks about the probability of accepting the null hypothesis when it is not true (i.e., non-zero values of the mean in his example).

YOU ARE WRONG, Jack Tomsky

From Herman Rubin to Richard Ulrich (a few yers ago):


The point null hypothesis is always false. If the
sample size is not too large, it can be a reasonable
approximation, but it is still not the precise p-value
which gives the consequences of incorrect rejection.

AS YOU EASILY WOULD GOT, IF YOU WAS A LITTLE INTELLIGENT, Prof. Herman
Rubin disagrees that one can achieve by Hypotheses Testing the *
miracle * that consists in find a parameter value exactly.
I repeat : contact him and get what he thinks about. I DO NEED NOT, IT
IS CLEAR CRYSTAL FOR ME.

Professor Rubin has said that the null hypothesis can be accepted even if it is false and has a probability of doing so.

YOU ARE COMPLETELY MAD.
Tell nim to post his conclusion, absoutelly contrary to what he had
post same time ago.

Professor Rubin wrote the following in the link I provided.

"To take a simple example, suppose one is testing that the mean of a normal distribution is exactly 0. Then the probability of rejecting the null hypothesis if it is true must be balanced against an integral of the probability of accepting this hypothesis over the non-zero values of the mean with respect to some measure. It is not that hard to proceed from this type of approach."


He would not be interested in the probability of accepting the null hypothesis if it were always zero.
