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)

[edit] 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
