Description Usage Arguments Value Examples
This function will produce an optimal rotation vector for some design. It will produce Resolution IV if possible and if not will find a minimal aberration. If multiple minimal aberration designs exist it will randomly choose one and ignore any "desirability" between factors.
1 | opt_rotation(design)
|
design |
This needs to be a coded design matrix using (0,1,2) where each row corresponds to one treatment. |
It will produce a list
Rotation Vector |
The first element of the list will be the optimum rotation vector and a small message whether Resoluiton IV is obtainable or if this is minimal abberration |
psuedo-design matrix |
This is the fake design matrix which is the coded effects of length 3 that are aliased with the intercept in the original design. This will not neccessarly be a regular fractional factorial design (hence psuedo) |
