Thanks for your comments. To be honest, for me the term "opitmal" (which seems not to be a very good term) reffered completely to the task of minimizing sample size without risking to not be able to reject the "null hypothesis". What could be another definition of optimal in connection with sample size? ================================================================= Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =================================================================
