Comments

There was a comment: There is a theorem I think - help appreciated immediately after the sentence

The squared-error loss function had been used by John von Neumann and Oskar Morgenstern in the 1930s.

I have removed this, as it is conversational and not part of the article's substantive material. -- JordanSamuels 13:57, 1 September 2006 (UTC)

Further Comment: I removed the other quoted statement,

The squared-error loss function had been used by John von Neumann and Oskar Morgenstern in the 1930s.

and added a brief history of loss functions in the loss-function subsection.Kiefer.Wolfowitz (talk) 16:32, 2 June 2009 (UTC)

I have added 'citation needed' to introduction, as there is nothing in the article that is critical of Taguchi methods or why it is controversial. -- stonemaccas

Further Comment: Some criticisms appear in the introduction and in footnotes. The introduction has been written to be more specific, replacing "conventional Western", etc. Kiefer.Wolfowitz (talk) 16:32, 2 June 2009 (UTC)Kiefer.Wolfowitz (talk) 18:55, 2 June 2009 (UTC)

A lot of marketing companies say the use the "Taguchi method" in order to calculate their results for multivariant testing. There doesn't seem to be any mention of how they do this at all in this articule or what that calcuation consists of.

Spam links

Could someone please check the external links? I was patrolling with Vandal proof and its possible that the last edit prior to my dated signature is a spam link to an advertising / commercial website. I don't know enough about this subject to tell. Thanks. Richard Harvey 06:43, 11 November 2006 (UTC)

Needs work

I agree that this page needs work (although I don't agree regarding the usefulness of the Taguchi method, I'm sceptical to most statistical methods and think they are usually better to replace by common sense). I was forced to use Taguchi at work and didn't get any valuable help at Wikipedia for once. The following pages contain interesting info: http://www.ee.iitb.ac.in/~apte/CV_PRA_TAGUCHI_INTRO.htm http://www.itl.nist.gov/div898/handbook/pri/section5/pri56.htm http://best.me.berkeley.edu/~aagogino/me290p/f98/slides/Taguchi/airplane.html http://www.isixsigma.com/library/content/c020311a.asp

I'd escpecially like to see some focus on how the so-called othogonal arrays (which basically are just arrays of tests all of which should be independant of eachother) are used etc. The information in Wikipedia is too general, and most examples I found at other pages (isixsigma for instance) are illustrative but don't help at all in understanding the details of the analyses.

Sorry I'm only able to point out the weaknesses, hope someone else will find interest to update this page. Even though I don't like the method, it would be useful to get help in understanding it from Wikipedia, so that I can argue more efficiently why I don't like it..

Landing Page Optimization

Reasons for this undo:

• The page linked to does not even mention the term "Taguchi methods".
• The text linked to is not a reliable source, but a promotional text on a website, linking to a service provider's website.

Please do not re-add this link without prior discussion. Thank you. Jayen466 15:49, 4 August 2008 (UTC)
