Dunnett's test
The real obstacle would seem to be the distribution of the many-one t-statistic. This doesn't seem to be available from any of the standard subroutine sources (apstat and toms). Miller's book cites the tables from a 1964 paper by Dunnett - I browsed through it earlier today and it seemed that the density can be calculated explicitly, but you need numerical integration to get the CDF. Anyone have a handful of spare evenings to code this up? -- O__ ---- Peter Dalgaard Blegdamsvej 3
The distribution in question is a certain type of multivariate t. Dunnett himself provided FORTRAN code for calculating quantiles of that distribution, in _Applied Statistics_ (1989). [It's Algorithm AS251.1.]. My copy of the code (downloaded from StatLib, I think) also has a simple driver/demo program by Dunnett, dated 10Apr1995.
the multivariate t distribution is available in package mvtnorm (based on the work by Genz & Bretz) Torsten
