Respiratory health and air pollution: additive mixed model analyses.

摘要: SUMMARY We conduct a reanalysis of data from the Utah Valley respiratory health/air pollution study Pope and co-workers (Pope et al., 1991) using additive mixed models. A relatively recent statistical development (e.g. Wang, 1998; Verbyla 1999; Lin Zhang, 1999), methods allow for smooth functional relationships, subject-specific effects time series error structure. All three these are apparent in data.
