Description Usage Arguments Details Value Note Author(s) See Also Examples
Generates a response surface design containing a cube, centerCube, star and centerStar portion.
1 2 |
k |
integer value giving the number of factors. By default |
p |
integer value giving the number of additional factors in the response surface design by aliasing effects. |
alpha |
character string - alpha shoud be “rotatable” (default), “orthogonal” or “both”. If “both” values for cc and cs will be DISCARDED. |
blocks |
integer value giving the number of blocks in the response surface design. |
cc |
integer value giving the number of centerpoints (per block) in the cube portion (i.e. the factorial 2^k design) of the response surface design. |
cs |
integer value giving the number of centerpoints in the star portion (alpha) of the response surface design. |
fp |
integer value giving the number of replications per factorial point (i.e. corner points e.g. (-1,1)). |
sp |
integer value giving the number of replications per star point (i.e. alpha). |
faceCentered |
logical value wheter to use a faceCentered response surface design or not (i.e. alpha = 1). |
Generated designs consist of a cube, centerCube, star and a centerStar portion. The replication structure can be set with the parameters cc (centerCube), cs (centerStar), fp (factorialPoints) and sp (starPoints).
rsmDesign
