Character Coding and Inapplicable Data
Open accessAbstract
Inapplicable character states occur when character complexes are absent or reduced in some of the taxa. Several approaches have been proposed for representing such states in a character matrix so that the inapplicable condition has no effect on the placement of taxa and/or the applicable states are independent and not redundant. Here we examine each of these approaches and demonstrate that all have shortcomings. Coding inapplicables as "?" (reductive coding), although flawed, is currently the best way to analyze data sets that contain inapplicable character states.

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.
