Results for the model that evaluates the number of collisions as a function of the characteristics of the immediately surrounding land cover the buildings.
| Coefficients | Estimates | Std. Error | z-value | 95% Conf. Int. | p-value [Pr(>|z|)] | |
|---|---|---|---|---|---|---|
| Lower | Upper | |||||
| γ0 (Tall vegetation) | −0.32 | 0.28 | −1.64 | 1.84 | 2.19 | 0.244 |
| γ1 (Short vegetation) | −0.67 | 0.56 | −1.20 | −0.94 | −0.13 | 0.231 |
| γ2 (Urban) | −1.22 | 0.37 | −3.30 | −1.30 | −0.71 | <0.001 |
The estimated values (natural logarithm scale) of the intercept and regression coefficient of each variable, the standard error, the z-value, and its associated p-value, and the lower and upper limits of the 95% confidence interval are shown. Significant p-values are highlighted in bold. γ0 is the coefficient representing the tall vegetation (trees and shrubs).
γ1 is the regression coefficient for environments with a higher proportion of short vegetation (grasses), and γ2 is the regression coefficient for urban environments (roadways and buildings).
