Fig. 2

Data A250. Plots of deviance differences for each model comparison against observed values for variables x5 and x6. A logarithm scale was used for variable x6 to ease visualization due to extremely large values. Please note that y-axis scales differ. Two threshold values, representing the significance levels α = 0.05 and α = 0.01, are shown on the plots as horizontal solid and dashed lines, respectively. Please note that the test of FP2 vs linear and FP2 vs FP1 may not be relevant if the test of FP2 vs Null is not significant. Nevertheless, we will always show the full panel
