A reported number of clusters or "types" can then be tested against what the data's own margins and covariance already produce, using any clustering pipeline. A t-copula option adds tail dependence to the null, so that an apparent excess of clusters can be checked against a heavier-tailed alternative before it is read as evidence of types. Implements the matched-null procedure of Meng (2026) "Types Without Taxa" <https://osf.io/2ekcg>.https://github.com/r-universe/haomeng797-ship-it/actions/runs/29971075524Thu, 23 Jul 2026 00:12:17 GMTmatchednull0.1.0.9000successhttps://haomeng797-ship-it.r-universe.devhttps://github.com/haomeng797-ship-it/matchednullmatchednull.Rmdmatchednull.htmlTesting a cluster count with matched nulls2026-07-05 05:16:142026-07-12 13:41:48
