论文摘要
椭圆形对称性的假设在许多理论发展和应用中具有重要的作用，因此能够测试该假设是否真的成立是至关重要的。文献中已经提出了有关此问题的各种测试。据我们所知，它们都没有在R中实施。本文的重点是实施了几种知名的椭圆形对称测试以及最近的一些测试。我们用真实的数据示例演示了测试过程。
The assumption of elliptical symmetry has an important role in many theoretical developments and applications, hence it is of primary importance to be able to test whether that assumption actually holds true or not. Various tests have been proposed in the literature for this problem. To the best of our knowledge, none of them has been implemented in R. The focus of this paper is the implementation of several well-known tests for elliptical symmetry together with some recent tests. We demonstrate the testing procedures with a real data example.
