Fig. 7. The fit of common dolphin takes to area 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 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). |
