This package offers single\nsample tests for the eigenvalues of the population mean or the\neigenvalue-multiplicity of the population mean. For k-samples,\nthis package offers tests for equal eigenvalues between\nsamples. Included is support for matrices with constraints\ncommon to geophysical tensors (constant trace, sum of squared\neigenvalues, or both) and eigenvectors are usually considered\nnuisance parameters. Pivotal bootstrap methods enable these\ntests to have good performance for small samples (n=15 for 3x3\nmatrices). These methods were developed and studied by Hingee,\nScealy and Wood (2026, ).\nAlso available is a 2-sample test using a Gaussian orthogonal\nensemble approximation and an eigenvalue-multiplicity test that\nassumes orthogonally-invariant covariance.", "URL": "https://github.com/kasselhingee/TFORGE", "RdMacros": "Rdpack", "License": "GPL (>= 3)", "Encoding": "UTF-8", "Roxygen": "list(markdown = TRUE)", "RoxygenNote": "7.3.3", "LazyData": "true", "VignetteBuilder": "knitr", "Repository": "https://kasselhingee.r-universe.dev", "Date/Publication": "2026-03-26 10:19:53 UTC", "RemoteUrl": "https://github.com/kasselhingee/tforge", "RemoteRef": "HEAD", "RemoteSha": "1dcf48670d5b0070bdd7bc4ec4477eeada134dab", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-25 07:15:47 UTC", "User": "root" }, "Author": "Kassel Liam Hingee [aut, cre] (ORCID:\n),\nArt B.
