Description Available analysis options Author(s) References

This is a brief explanation on the menu for analysis of designs for quantitative factors.

The menu item *Response surface model ...* creates a response surface
analysis with first order (FO) terms, and potentially also two-factor interactions
(TWI) and/or pure quadratic (PQ) terms. The resulting object has class `rsm`

and can be postprocessed with the subsequent menu items.

The menu item *Steepest slope ...* supports moving the experimental range
towards a more promising area, based on a first order model or on a second order
model with a saddle point.

The menu item *Plot response surface ...* supports creation of contour,
perspective or image plots of a response surface model,
and can also be used for linear models with quantitative variables.

It is of course also possible to use other analysis facilities within the R-commander,
or to use the command-line facilities offered in package `rsm`

and elsewhere.
