Fig. 12From: Modeling size-density trajectories of even-aged ash (Fraxinus excelsior L.) stands in France. A baseline to assess the impact of Chalara ash diebackNormal (QQ) plot of the normalized residuals of the fit of Eq. (1) to the ash stand data with the linear constraints on the inflection points. The linearity of the relationships suggested there was no evidence for a significant departure from normality of the withingroup (treatment) errorsBack to article page
