Subject: distance coefficient for amatrix with ngative valus

One order of the usual coming right up!
1 course of "Why does XXX not work for you?" a la francaise, where XXX
is, in your case, the Euclidean distance. Specifically, any metric
worth its salt (in a normed space) satisfies dist(a,b) = dist(a+c,b+c)
so why are negative values a problem?...
2 sides: a "Minimal Working Example" with a light buttery sauce and a
fried "what package/code are you using"
and, for desert, a Winsemian special of: "read the posting guide!"

even as he types

Are there any other coefficient works with negtive values.Also I cannot get summary out put (the eigen values) for PCO as for PCA.
