因为CORR算是比较直观的一种线性相关性的度量，但是CORR也因此容易失去一些COV本来的特性，比如时间序列里平稳性就不能用CORR来决定。。。
In this paper, we derive the distributions of unbiased estimators and consider hypothesis testing for independence. Representative test statistics such as the likelihood ratio criterion, Wald statistic, Rao’s score statistic, and gradient statistic are derived, and we evaluate the accuracy of the ...
we proceed to test individual hypotheses such as αi= αjor βl= βk Consider the hypothesis H0: b = 0 Consider the hypothesis H1: α1= α2= ··· = αp(= α,say) Consider the hypothesis H2: β1= β2= ··· = βq= β If F in (ii) and F in (iii) are significant,...

parameterize the K precision matrices as Ω(k) = Θ ∘Γ(k) with Θ representing the overall network structure and Γ(k)’s representing the group-specific difference in the structure. 3.2 Hypothesis testing When studying the covariance matrix of a multivariate Gaussian population, there are tw...
As an application, hypothesis testing for trends in global annual temperature series is performed.

The results of this section are consistent with the hypothesis of the previous section Features of Temporal Domain, which indicates that the variations of the relationship between different channels over time play an important role in the classification. Based on research on this hypothesis, the feasi...
For the identity hypothesis, deviation of Λ from one is zero. The functionals (John, 1971; Nagao, 1973) can be defined as (42)U(Λ)=1p∑k=1pλkλ¯−12=1ptrΣtrΣ/p−I2,V(Λ)=1p∑k=1pλk−12=1ptrΣ−I2. In the traditional setting when p < n, the sample ...
