Help: Strange MDS behavior
Hi!
I have a dissimilarity matrix X and try to compare it with X' =
dist(cmdscsale(X,k)).
If I increase k, I should expect that the error (or fit) should
monotonically decrease, right.
Here is a sample code;
library(mva)
set.seed(12345)
x <- as.matrix(dist(matrix(rnorm(100),ncol=10,byrow=T)))
# x[1,2]<-x[2,1]<-1000 ## <<--** 1
# x[5,6]<-x[6,5]<...
