Figure 8. Function estimates for the chlorophyll- a concentration.

Figure 8

Analysis of the NLA Data. The five panels contain the function estimates for the chlorophyll- a concentration (computed from 100 bootstrap samples). In case of beta regression, estimates present the effects of the chlorophyll- a concentration on the mean parameter Inline graphic. Black lines correspond to the mean and the 0.05 and 0.95 quantiles of the function estimates. For reasons of interpretability, the range of the x-axes was restricted to the lower Inline graphic of the sample values.
