Talk:Genichi Taguchi

References

I added a tag about references. Taguchi may be extremely important, but this writeup has hallmarks of non-NPOV, e.g., "it was controversial, but is now accepted as important", "very influential", the only external link is a photograph (!), etc. References would help support strong claims like that, or facts would help make this more NPOV.

Say, I've added several internal citations, and therefore removed the unsourced tag. I'm thinking that wasn't the proper procedure, and I should ask others to judge whether the sources are sufficient to warrant the removal of the tag. What do you think? Kjtobo (talk) 16:33, 30 April 2009 (UTC)

Kjtobo, I'm not sure whether to remove the BLP sources tag. The article looks somewhat better to me, although I haven't reviewed in depth. I wish it had sources for the strongest or most positive statements:

1. "but others have accepted many of the concepts introduced by him as valid extensions to the body of knowledge."
2. "Taguchi's work includes three principal contributions to statistics:"
3. "he was beginning to consult widely in Japanese industry"
4. "Taguchi has made a very influential contribution to industrial statistics"
5. "growing enthusiasm for his methodology..."

Again, I'm not saying he hasn't done these things. It's just all the positive statements are unsourced. dfrankow (talk) 17:24, 30 April 2009 (UTC)

Let's keep the tag. While I think the article is broadly correct, more sources will certainly improve it. [1] Jayen466 18:23, 30 April 2009 (UTC)

141.140.6.60

This sentence seems to be the central one of the whole article:

Taguchi's innovation was to replicate each experiment by means of an outer array, itself an orthogonal array that seeks deliberately to emulate the sources of variation that a product would encounter in reality.

Unfortunately, the sentence is utterly unintelligible. What is an "outer array" or an "orthogonal array"? Could we see a tiny example? 141.140.6.60 00:28, 8 May 2005 (UTC)

The article keeps mentioning "Western statisticians" at least a dozen times. Is there any palpable distinction between "Western" and "Eastern" statisticians, and if so, do the Eastern statisticians accept his methods? 141.140.6.60 00:32, 8 May 2005 (UTC)

Loss functions - theorem

Italicized part (from a previous editor) moved here from main page:
The squared-error loss function had been used by John von Neumann and Oskar Morgenstern in the 1930s. There is a theorem I think - help appreciated

Overlap between Genichi Taguchi and Taguchi methods

Is there any reason that the page 'Genichi Taguchi' is almost identical to the page 'Taguchi Methods'? The only difference is the first paragraph and the section on 'Life'. 202.180.110.18 (talk) 22:38, 17 June 2008 (UTC)

Well spotted; I have inserted a brief summary here, with a link to the main article. We should not have the same text in both articles. --Jayen466 23:05, 17 June 2008 (UTC)
