Table 3. Selection frequencies of covariates for both the mean (μ) and variability (φ) parameters in the boosted beta regression model for the overall fix success rate.
| Variable | Selection frequency | |
|---|---|---|
| μ | φ | |
| Brand | 43% | 20% |
| Time-to-fix | 19% | 10% |
| Height | 10% | |
| Burrowing/Hibernating | 10% | |
| Forest Density | 10% | 10% |
| Forest type | 5% | 20% |
| Forest cover (qualitative) | 5% | |
| Forest cover (GlobCov) | 20% | |
| Purchase date | 10% | |
| 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.
