Coefficients of the best spatial hierarchical Bayesian model for the geographic distribution of genetic diversity of Iberian Arabidopsis thaliana
| HS ≈ 0 | HS > 0 | |||
|---|---|---|---|---|
| Variables | β | SD | β | SD |
| Intercept | 2.054 | 1.776 | 0.305 | 0.604 |

Entries (β ± SD) are given for the degenerate distribution with point mass and zero (binary data including populations with HS values ≈ 0) and a conditional-to-presence continuous process (continuous data including populations with non-zero HS values). The best model had a WAIC value of − 365.43 and a LCPO value of − 0.31. BIO15 is the precipitation seasonality and BIO18 is the precipitation of the warmest quarter
