Table 30.1.

Association between asthma hospitalization and log PM2.5 (β̂1) and elevation (β̂2). The four models above the line are fitted using maximum and quasi-maximum likelihood estimation, the two below are Bayesian hierarchical models (and assume a Poisson likelihood). The “Log-Linear Model” refers to model (30.1) while the “Aggregate Exposure Model” refers to model (30.15) using modeled exposures. “Convolution” refers to the model with non-spatial and spatial random effects modeled via an ICAR model.
