Stress with MDS
...definitions of the "stress" function.
So, same problem, several questions :
1. Statistical consideration : With "cmdscale" we get eigen values. What is
the best way to choose optimal dimensionality? With the eigen values and
corresponding GOF like we do with PCA ? If I compute stress1, does it make
any sense (I saw it in some publications)?
2. With isoMDS and nmds we get the final stress but i can't find the source
code so i don't know what is in the box. Obviously, I got different values
from isoMDS and nmds . I started from the same initial configuration

isoMDS vs. other non-metric non-R routines
Dear useRs,
last week I asked you about a problem related to isoMDS. It turned
out that in my case isoMDS was trapped. Nonetheless, I still have
some problems with other data sets. Therefore I would like to know if
anyone here has experience with how well isoMDS performs in
comparison to other non-metric MDS routines, like Minissa.
I have the feeling that for large data sets with a high
