Mean Difference Between Outdoor UFP Number Concentrations Predicted from New Combined LUR-CNN Models and Previous Models for Toronto and Montreala
| City | Mean Difference (95% CI) |
Slope of Linear Model | Intercept of Linear Model | R 2 |
|---|---|---|---|---|
| Toronto | −17,054 (−17,171, −16,938) |
0.70 | 21,124 | 0.19 |
| Montreal | −14,783 (−14,882, −14,683) |
0.97 | 15,158 | 0.18 |
CI = confidence interval; CNN = convolutional neural network; LUR = land use regression; UFP = ultrafine particles.
a Mean difference calculated as new model minus previous model. Previous models are described in references 12 and 13.
