Approximating the Probability of Identifying the Most Effective Treatment for the Case of Normal Distributions Having Unknown and Unequal Variances.
Wilcox, Rand R.
Educational and Psychological Measurement, v43 n1 p43-51 Spr 1983
When comparing k normal populations an investigator might want to know the probability that the population with the largest population mean will have the largest sample mean. This paper describes and illustrates methods of approximating this probability when the variances are unknown and possibly unequal. (Author/BW)
