You say:
“””Fausto’s students search in vain for an assignable cause but there are none to be found because the process is inherently exponential.”””
PROVE that if the data are “””inherently exponential””” there are NO Assignable causes!!!
YOU forgot that T CHARTS Control Limits are WRONG in Minitab!!!!!!!!!!!!!![Read more]

Are you all very happy of this big drawback of MINITAB?

Fausto Galetto started the topic Minitab TCharts Have Wrong Control Limits, Exponentially Distributed Data in the forum General 4 days, 10 hours ago
WHY Minitab Inc. Managment do not take suitable Corrective Actions about their
“””MINITAB T Charts have WRONG Control Limits, Ewhen the data arexponentially Distributed”””?
They have been informed about the problem!!!!
What is your opinion?

You wrote: Statisticians use the terms “degrees of freedom” to describe the number of values in the final calculation of a statistic that are free to vary.
This is explanation is due to (whom I call) “normal drugged statisticians” (they are the people that have their “statistical” knowledge based on the Normal Distributed data).

I was challenged to write a paper and to have it PEER REVIEWED, BECAUSE the “discussants in the post” did not have enough knowledge of any method for dealing “correctly” with T Charts.
THEY did not believe that I am right…
THEY think that only PEER REVIEWED papers are good!
It false!
I suggested my documents in order to GIVE THEM…[Read more]

I am very sorry for you.
Good learning is forbidden to you: when I cite some of my papers they are cancelled …
On the contrary, wrong papers are allowed:

Did you find the errors in that PEER REVIEWED paper?

In these days, I read several papers about “””Charts with exponential distributed data”””: full IGNORANCE!!!
IF YOU WANT….
you can find some hints in my paper

VERY VERY GOOD paper… PEER REVIEWED by … INCOMPETENT …
 I will send my “rebuttal paper” to Quality Engineering.

The paper suggestedd by David007 proves that Peer Review Process does not assure “quality (????)” of the papers………………

As I said in a previous post (I do not remember “when”) THAT’S WRONG!!!!
THEORY is needed!!!!

AFTER several emails exchanged with MINITAB, here are the conclusions:
From MINITAB:
1. Discussing the topic of the theory behind the T charts are not covered by our free technical support,
2. and I would refer you to consult with your favorite statistician
3. or you can pay us for tutoring through our Statistical Consultin…[Read more]

@ All STATISTICIANS
I will write a Green&White&Red paper and I send it to a Statistics Journal HOPING that ti will be analysed by INTELLIGENT Peer Reviewers……….
The Correct THEORY is in my books.
I am not allowed by iSixSigma to provide links to my documents!!!
For the time being let you be informed that I informed MINITAB of their T Chart…[Read more]
