Dear all,
The Ngene Manual explains "optimal orthogonal in the differences" (OOD) designs, referring mainly to Burgess & Street (2005) and Street et al. (2005).
However, reading those papers I could not find any paragraph where the authors actually name their method OOD, although several other papers mentioning OOD always refer to these authors.
Does anybody have any idea in which source the name of this design method came up first?
Thanks a lot in advance!
