  "Version": "0.1",
  "Description": "Matrix-variate covariance estimation via the\nKronecker-core decomposition. Computes the Kronecker and core\ncovariance matrices corresponding to an arbitrary covariance\nmatrix, and provides an empirical Bayes covariance estimator\nthat adaptively shrinks towards the space of separable\ncovariance matrices. For details, see Hoff, McCormack and Zhang\n(2022) <arXiv:2207.12484> \"Core Shrinkage Covariance Estimation\nfor Matrix-variate data\".",
