The package employs the Fourier transformation method\nproposed by Samadi and De Alwis (2023)\n and the Nadaraya-Watson kernel\nsmoother method proposed by Park et al. (2009)\n for estimating the TS-CMS. The\npackage provides tools for estimating distances between\nsubspaces and includes functions for selecting model parameters\nusing the Fourier transformation method.", "License": "GPL-2 | GPL-3", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.2.3", "VignetteBuilder": "knitr", "NeedsCompilation": "yes", "Packaged": { "Date": "2026-05-19 07:39:53 UTC", "User": "root" }, "Author": "Tharindu P.
