Abstract:
|
We study the problem of hypothesis testing in high dimensional sparse regression. We study the properties of a class of tests introduced for this purpose. The results are derived in a high dimensional regression setting with p variables and we suppose that under the alternative only k of them are non-zero where k is much smaller than p.We identify different classes of alternatives under which the proposed classes of tests can be classified to have differential behavior of power functions.The results are non asymptotic in nature as we provide finite sample bounds on the testing errors. As a result we also derive the relative efficiencies of the tests with respect to the classical tests in the high dimensional sparse regression setting.
