I have recently read a paper where the authors carried out a
"Multidimensional Space Analyses".

Essentially the authors were comparing 6 different aspects of a
product, and used a formula where they took the square root of the sum
of various parameters squared.  A low index indicated a good product
and a high index a bad product.

Are there any good references on this, and is it a well recognised
method of producing a single index figure from a number of different
parameters ?
