abstract: The eigenvalues of observed symmetric matrices are often of intense scientific
  interest. This package offers single sample tests for the eigenvalues of the population
  mean or the eigenvalue-multiplicity of the population mean. For k-samples, this
  package offers tests for equal eigenvalues between samples. Included is support
  for matrices with constraints common to geophysical tensors (constant trace, sum
  of squared eigenvalues, or both) and eigenvectors are usually considered nuisance
  parameters. Pivotal bootstrap methods enable these tests to have good performance
  for small samples (n=15 for 3x3 matrices). These methods were developed and studied
  by Hingee, Scealy and Wood (2026, <https://doi.org/10.1080/01621459.2025.2606381>).
  Also available is a 2-sample test using a Gaussian orthogonal ensemble approximation
  and an eigenvalue-multiplicity test that assumes orthogonally-invariant covariance.
