| Abstract: |
| In this paper, we investigate the problem of testing the conditional symmetry of a random vector given another random vector. We propose a new test based on the concept of conditional energy distance. The test statistic has the form of a U-statistic with random kernel. By using the theory of U-statistic, we prove that the test statistic is asymptotically normal under the null hypothesis of conditional symmetry and consistent against any conditional asymmetric distribution. |
| Key words: conditional symmetry test conditional energy distance U-statistic with random kernel consistent asymptotical normality |
