Table A.1.
Adequacy test for the basis dimension for the two smooth terms.
| term | k′ | edf | k-index | p-value |
|---|---|---|---|---|
| f1([Fe/H], [α/Fe], log g) | 189 | 85.14 | 1.01 | 0.78 |
| f2(M) | 14 | 5.79 | 0.99 | 0.37 |
k′ is the dimension of the basis minus 1; edf are the effective degree of freedom of the smooth; k-index is the test statistic; p-value provides the statistical significance of the test.
