Notes.
The bias, σMAD and fraction of outliers η are defined in Sect. 4.1. The values are averaged over five test samples, except in the cases marked with a ⋆ where there is only one. The CRPS and PDF width are defined in Sect. 4.3. The SZ was identified as a small region of the SDSS with above average bias (see Sect. 6.4). It has been removed by default in all other cases below the “SZ removed” line.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
