Three species of Webera and Pohlia described from China were reduced to new synonyms of other species of Pohlia. Webera ciliifera Broth. is a synonym of Pohlia elongata Hedw., W. pygmaea Broth. is a synonym of P. minor Schleich. ex Schwaegr. and P. subflexuosa Broth. is a synonym of P. flexuosa Hook.
Non-standard errors
(2021)
In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty: non-standard errors. To study them, we let 164 teams test six hypotheses on the same sample. We find that non-standard errors are sizeable, on par with standard errors. Their size (i) co-varies only weakly with team merits, reproducibility, or peer rating, (ii) declines significantly after peer-feedback, and (iii) is underestimated by participants.
