Anyone have the reference to the "Waller-Duncan" test? Is this the
multiple range test?

Other references (at-hand):

Comparisions and Multiple Tests Using the SAS System_ (Cary, North Carolina:

Bayesian k-ratio t Test. in _Principles and Procedures of Statistics: A
Biometrical Approach_  Second Edition. (Tokyo: McGraw-Hill Kogakusha, 1980),
pp. 190-91.

This latter cites the following in addition:

D. O. Dixon & D. B. Duncan, Minimum Bayes risk t-intervals for multiple
comparisons.  _J Amer Stat Assoc_ 70:822-31, 1975.

As you can infer from the titles, the Waller-Duncan test is not Duncan's New
Multiple Range Test.
