Abstract: | Consider the partially balanced one-way layout for comparing k treatments μi,1?i?k, with a control μ0. We propose a new test which is similar to the test statistics of Marcus 1976. The powers of some tests of the equality of normal means against an ordered alternative. Biometrika 63, 177–183]. By simulation we find that the proposed test has a good power performance when compared with other tests. Moreover, it can produce confidence intervals for μi-μ0,1?i?k. |
