**Fig. 6.** The fit of white-sided dolphin takes to the SST and Depth categories (Tables 7 and 8). The horizontal line indicates the fit where the length is a function of the number of observations in the category. The vertical lines are two standard error bands. The SE bands for the high SST category are present with upper and lower bounds near zero but are not distinguishable in the graph due to the very large number of zeros relative to the total number of observations in this category. The jittered black circles are the partial deviance residuals for all observations. Solid black bars or ‘rug plot’ on the x-axis represent sample sizes at each category (Splus 6.2). |
