Observational epidemiological studies analyzed via spatial regression methods are often affected by spatial confounding. We formulate an adjustment strategy based on spectral methods, by considering eigendecomposed conditional autoregressive models. We model exposure and confounding variable using different commonly used spatial models, to study the extent to which bias due to spatial confounding can be adjusted under different specifications.

Abstract
Observational epidemiological studies analyzed via spatial regression methods are often affected by spatial confounding. We formulate an adjustment strategy based on spectral methods, by considering eigendecomposed conditional autoregressive models. We model exposure and confounding variable using different commonly used spatial models, to study the extent to which bias due to spatial confounding can be adjusted under different specifications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
