Spearman correlation coefficient ρ between data properties and performance.
| Recall | Precision | |||
|---|---|---|---|---|
| ρ | p-value | ρ | p-value | |
| Cluster size | 0.30 | 0.12 | 0.27 | 0.17 |
| ⟨σ⟩ | −0.79 | < 2 × 10−6 | −0.77 | < 3 × 10−6 |
| [Fe/H] | 0.38 | 0.05 | 0.37 | 0.05 |
Notes. Spearman correlation coefficient ρ and its corresponding p-value between cluster relative size, mean abundance error and mean metallicity of every cluster and recall and precision. The p-value roughly indicates the probability of an uncorrelated system producing datasets that have a Spearman correlation at least as extreme as the one computed from these datasets.
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.
