Fig. 8From: Relation between temperature and suicide mortality in Japan in the presence of other confounding factors using time-series analysis with a semiparametric approachThe GAM-estimated effect of maximum temperature on suicide mortality for different methods. This is an example of the Tohoku region, where the suicide mortality was highest. The continuous lines are the function estimates, and the shaded areas delimit the 95% confidence interval for the function. The numbers on each y-axis are the effective degrees of freedom of the term being plotted. Smoothing parameters are estimated by UBRE/AICBack to article page
