Fig. 2

Type I error for the copollutant (pollutant 2) in a copollutant model (RR1 = 1.05, RR2 = 1), with exposure measurement error. For x-axis labels, top row indicates the main pollutant (pollutant 1), bottom row indicates the copollutant (pollutant 2). Red line indicates type I error = 0.05. Overall point estimates shown are the mean over 1000 estimates; error bars indicate the 95th confidence interval for the 1000 estimates. a Spatial measurement error (δspatial). b Population measurement error (δpopulation). c Total measurement error (δtotal)
