Hi all,

If one wants to plan a randomization scheme for a 4 way study, how does one go about assigning the treatments order in each of the 4 sequence (yes, use 4)? A 4 treatment study will have 24 possible sequence so the selection of which 4 sequences to use should be randomly selected, correct? So I should have a SAS routine to select the sequences first and then another to generate the study randomization scheme?

Thanks
John
