摘要

We investigate a new tool for measuring whiteness. We first introduce a quantity which has suitable properties for constructing a test for whiteness. We derive such a test and its distribution under the null hypothesis and the non-null one. We provide the power of the new test, a useful tool for performance evaluation. Finally, we experimentally compare our test to the portmanteau test for checking whiteness. Results show that our test outperforms the portmanteau one ln all cases and particularly for small sample sizes. Copyright.
