Figure 6

Conditional wormplots of the negative binomial regression model (Eq.8.51) for different groups of the predictor variable DWT . Deviations from standard normal quantiles are displayed for DWT values less than 2 m, 2–3 m, 3–4 m and more than 4 m in depth (from lower left panel to upper right panel). Curved dashed lines indicate the boundaries of the 95% confidence intervals of the standard normal quantiles. The curved solid gray lines are polynomial trend curves that highlight potential pattern in deviation from standard normal quantiles.
