Overview

About

Covariance is of universal prevalence across various disciplines within statistics. We provide a rich collection of geometric and inferential tools for convenient analysis of covariance structures, topics including distance measures, mean covariance estimator, covariance hypothesis test for one-sample and two-sample cases, and covariance estimation. For an introduction to covariance in multivariate statistical analysis, see Schervish (1987) doi:10.1214/ss/1177013111.

Changes in 0.5.7
  • Replaced the external generalized-eigenvalue dependency with internal symmetric-definite matrix-pair helpers based on a Cholesky reduction.
  • Removed an obsolete native generalized-eigenvalue wrapper.
  • Corrected positive-definite hard-threshold selection and now verify every returned covariance estimate against the documented eigenvalue tolerance.
  • Corrected Power-Euclidean distances and means for negative powers, fixed Procrustes size-and-shape distances, and covered scalar and one-slice inputs.
  • Corrected bandwidth selection and matrix construction in the Banerjee, An, and Lee banded precision estimators.
  • Corrected graphical-lasso BIC scoring and return the sparse positive-definite ADMM estimate.
  • Centered covariance diagonality tests, restored the documented Cai test result field, and added minimum-sample and degenerate-data checks.

  • Sequential cross-validation and BIC selection no longer create socket workers; parallel paths now clean up workers without changing the caller's global foreach backend.
