✦ Synopsis

By ueing Monte Carlo studies, this paper cornpaw the Welch test, the Jam-test and the Brown-Forsythe teat for comparing several means under heteroscedeeticity. It appeara that all the testa are quite robust with respect to departure from normality. The Brown-Foraythe test is at least as good as the Jamee teet and the Welch b e t ; but the differences are 80 emall that the choice is immaterial for practical p u p o w .

I n this paper we consider a covariance model under hetermcadastic variance8 and propose a procedure for tasting treatment effects. A simultaneous procedure for comparing the treatment effects is also developed. Some Monte Carlo studies indicete that the effects of departure from normality may not b
