FFdes
Level 5 fractional factorial designs
Description
Computes level 5 fractional factorial designs for up to 120 factors using the agorithm of Sanchez and Sanchez (2005), and optionally central composite designs.

Arguments
size | number of factors up to 120. |
ccd | if |
Details
Basically a translation of the code provided in the appendix of Sanchez and Sanchez (2005).
