Table 1 Model comparisons of QuaSSE analyses of continuous drivers with significant predictive ability in the XGBoost model, with AIC scores of the best-fitting and null models
From: Identifying the multiple drivers of cactus diversification
Variable and sample size | Best-fitting model | ΔAIC of best fitting model versus constant model (null) | Midpoint value (back-transformed to the original scale if they were log-transformed), and drift parameter |

Soil sand content (n = 850) | Modal with drift | 65.53 | 48.38%, 0.00045 |
Plant size (height or length) (n = 750) | Modal with drift | 76.72 | 45.74 cm, −0.060 |
Isothermality (n = 850) | Modal with drift | 237.10 | 0.55, 0.0012 |
Geographic range size (n = 850) | Modal with drift | 307.86 | 0.23 AOO, −0.45 |
