Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The Ordovician radiation started in some parts of the world (China, Gondwana) in the late Cambrian, when Baltica was in higher latitudes and far away from tropical waters ideal for speciation and diversification; when Baltica moved to lower latitudes during the Middle Ordovician, diversification rates 'exploded' and the numbers of taxa in the PBDB are much higher for this interval because a large

    “Similarly, the Ordo­ vician radiation started in some parts of the world (China, Gondwana) in the late Cambrian, when a palaeocontinent such as Baltica was in higher latitudes and far away from tropical waters that are ideal for speciation and diversification (see below, Fig. 6). Logically, when Baltica moved to lower latitudes during the Middle Ordovician, the diversification rates 'exploded '”
  • The PBDB is not only biased, with a large majority of data from the western world, but also the data from North America (palaeocontinent Laurentia) largely dominate the 'global' database, followed by data from northern Europe (Baltica and Avalonia), with the 'global' PBDB curve reflecting actually the evolution of marine life during the early Palaeozoic of the 'western' world.

    “In the latter study, it became clear that the PBDB is not only biased, with a large majority of data from the western world, but also that the data from North America (palae­ ocontinent Laurentia) largely dominate the 'global ' database, followed by the data from northern Europe (Baltica and Avalonia), with the 'global ' PBDB curve reflecting actually the evolution of marine life”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
