Comparing the performance of air pollution models for nitrogen dioxide and ozone in the context of a multilevel epidemiological analysis
... Standard measurement error theory considers two error types, that is, classical and Berkson. 34 Additive classical error is evidenced by a high variance ratio (model versus “true”) and generally leads to downward bias in ...
