Example text

Similarly,if the covariance matrix is a diagonal matrix, then univariate methods with unequal variances for the components may be used for any inference. For example, Dudoit et al. (2002) assumed that the covariance matrix is a diagonal matrix in their classification procedure without verifying that the data support this assumption. In fact, it is shown in Srivastava (2006b) that the data do not supp port this assumption. This also implies that if the global hypothesis H = ∩i=1 Hi , is rejected, the False Discovery rate (FDR) of Benjamini and Hochberg (1995) cannot be used to determine the components that may have caused the rejection of the hypothesis H unless the test statistics used in testing the hypothesis Hi are positively dependent, such as under the assumption of normality, the covariance matrix Σ is of the intraclass correlation form Σ = σ2 (1 − ρ)I p + ρ1 p 1 p where ρ ≥ 0 and 1 p is a row vector whose all entries are one 1 p = (1, .

P ) . 50) For local alternatives, we assume that 1 √ η = (nN) 2 δ, δ = O(1), and n = O( p) . 51) The asymptotic non-null distributions of the statistics TD and TBS are the same, and thus we give the non-null distribution of TBS . It is given by trδδ lim lim P1 (TBS > z1−α ) − Φ −z1−α + √ n 2pqa2 n→∞ p→∞ =0. 52) The asymptotic non-null distribution of the statistic TS+ is given by lim lim P1 n→∞ p→∞ TS+ − nq tr ∧ δδ √ √ > z1−α − Φ −z1−α + 2nq pa2 2nq =0. 53) The asymptotic non-null distribution of TSD is not available.
