Let π1,…,πp be p independent normal populations with means μ1…, μp and variances σ21,…, σ2p respectively. Let X(ni) be a simple random sample of size ni from πi, i = 1,…,p. Given the simple random samples X(n1),…, X(np) from π1,…,πp respectively, a test has been proposed for testing the homogeneity of variances H0: σ21=…σ2p, against the restricted alternative, H1: σ21≥…≥σ2p, with at least one strict inequality. Some properties of the test are discussed and critical values are tabulated. 相似文献

An observation ×o is to be classified into one of two normal populations φ1 and φ2. A classification rule, the Two-stage sample Rule, R(TS), whose probability of misclassification, P[MC], is independent of the common but unknown variance is proposed. Some optimal properties of R(TS) are also discussed and some values of P[MC | R(TS)], the probability of misclassification given the rule R(TS), are tabulated. 相似文献

Let π1 and π2 be two exponential populations with location parameters α and β respectively. It is shown that the probability of misclassification for the optimal rule, RE, depends on α and β only through their ratio α/β=r, and that the smaller the ratio r (i.e. the smaller α is compared to β), the greater the superiority of the optimal rule RE over the commonly used rule RN. When α and β are unknown, the sample-based version RE(s) of RE exhibits the same pattern of superiority over the sample-based RN(s) of RN. 相似文献
