  "Version": "0.1.1",
  "Description": "Kronecker-invariant tests for high-dimensional\nseparability testing of matrix-variate data, focusing on\nGaussian populations as benchmark cases. Tests whether the\npopulation covariance matrix is represented as a Kronecker\nproduct of row and column covariance matrices. Implements the\ntests based on the eigenvalues of the sample core whose test\nstatistics are invariant to the separable component of the\npopulation covariance matrix, referred to as\nKronecker-invariance. Tests constructed using the largest\neigenvalue and the separable expansion of the sample core and\napplying the extended likelihood ratio test for sphericity\ntesting to the sample core. For details, see Sung and Hoff\n(2025) <doi:10.48550/arXiv.2506.17463>.",
