Table 2. Selection frequencies of covariates for both the mean (μ) and variability (φ) parameters in the boosted beta regression model for the fix acquisition rate.
| Variable | Selection frequency | |
|---|---|---|
| μ | φ | |
| Height | 22% | |
| Purchase date | 19% | |
| Burrowing/Hibernating | 15% | |
| Time to fix | 11% | 20% |
| Forest density | 11% | 30% |
| Forest type | 11% | |
| Brand | 7% | 40% |
| Terrain ruggedness (qualitative) | 4% | |
| Terrain Ruggedness Index | 10% | |
The higher the selection frequency, the more important the covariate is in predicting either the mean or the variability of the fix acquisition rate.
