Dear list,

I have produced an nMDS plot with stress of 2.5 for first two dimensions. It
is my understanding this is _very_ poor support. When I run the procedure in
three dimensions (k=3), the stress value drops into the bucket and lands at
0.006. I have compared both plots and judging by feel alone I would say the
3D interpretation doesn't offer much more information than 2D (but see for
yourself: 2D<http://i53.photobucket.com/albums/g67/romunov/trash/nmds_3d.jpg>and
3D <http://i53.photobucket.com/albums/g67/romunov/trash/nmds_3d.jpg>). Would
it be sensible to use 3D plots for interpretation instead of the "common" 2D
based on stress value alone?

Cheers,
Roman
