Provides divergence_coefficient() for measuring separation between groups on continuous features, scatter_ellipse() for fitting covariance ellipses per class, transgression() for detecting ellipse overlap, and classify() for Bayesian posterior classification. These methods predate and are more general than the binary-character similarity coefficients of Sokal and Sneath (1963) that appear in other R packages.https://github.com/r-universe/akzhanberdi/actions/runs/28016124054Mon, 22 Jun 2026 18:32:08 GMTlyubishchev0.1.0successhttps://akzhanberdi.r-universe.devhttps://github.com/cran/lyubishchevlyubishchev.Rmdlyubishchev.htmlQuantitative Taxonomy with Lyubishchev's Methods2026-06-22 18:32:082026-06-22 18:32:08
