I would like to compare t treatments against a single control using Dunnett's test. My problem is that the variance is not homogeneous across the treatments.

  • Is it a problem for Dunnett's test?
  • If so, which method is recommended?
  • some R code available?

Apparently, unequal variances are not (in and of themselves) a problem.
