Results for the Pre-Delta-RCHR (Blue), the Delta-RCHR (Orange), and the Omicron-RCHR (Red). a-g: Accumulated local effects (ALE) of dynamic variables. Shaded areas in each plot indicate 95% confidence intervals. h-k: Estimated slopes for each static variables, the upper and lower band indicate 95% confidence intervals. m: Deviance explained for each model. ‘***’: variable significant at p < 0.001. ‘**’: variable significant at p < 0.01. ‘*’: variable significant at p < 0.05. ‘’: variable significant at p > 0.05
