This paper is concerned with test of significance on high dimensional covariance structures, and aims to develop a unified framework for testing commonly-used linear covariance structures. We first ...

In a mathematical approach to hypothesis tests, we start with a clearly defined set of hypotheses and choose the test with the best properties for those hypotheses. In practice, we often start with ...

Here we focus on explaining the temporal variations of 14 CO in the region between New Zealand and Antarctica by analysing the factors that control concentrations there. The lack of latitudinal ...
