Hello,
concerning the possible enhancements for S-Plus:
In my environnment, we often use experimental designs.
I have a licence of the DOX module, and find it very
convenient. It is however quite expensive.
I would suggest that DOX should be part of future S-Plus
versions, to promote via S-Plus the use of experimental
designs. The surface, contour and image functions for
Response Surface Designs need to be "Trellis-ized".
Mixture designs (where the ingredient factors sum up to
a constant) should also be integrated, with a plot function
to visualize the response surface in triangles (see the
book by Khuri et al.).
