Marginal coefficient effect plots for the eight most decisive model terms, selected by the highest Pr (term k in) values in Table 3. Values > 0 indicate a positive effect on the success of oak regeneration. Dashed lines show the location of the posterior median, and solid lines the location of the posterior mean. Darker colored areas show the 10% and 90% quantiles of the posterior distribution (corresponding to an 80% credible interval), lighter colored areas the 2.5% and 97.5% quantiles (corresponding to a 95% credible interval). The ticks on the x-axis mark the distribution of the data points over the data range
