The resulting design is orthogonal, however it may not be possible to have an equal number of runs in each group. Also, the factor you create in this way is not unaliased by two-factor interactions of the other factors.</P></BODY></HTML> Mon, 15 Sep 2014 17:16:19 GMT https://community.jmp.com/t5/Discussions/Can-I-have-a-3-level-categorical-factor-in-a-definitive/m-p/8899#M8885 bradleyjones 2014-09-15T17:16:19Z
