Table 2 Comparison of spatial and non-spatial models for predicting total mortality during days with prolonged dust events
Variables | Multivariate linear: predicted mortality on dusty days (95% confidence intervals) | Spatial error (lag 1): predicted mortality on dusty days (95% confidence intervals) | Spatial error (lag 2): predicted mortality on dusty days (95% confidence intervals) | Spatial error (lag 3): predicted mortality on dusty days (95% confidence intervals) |
