Figure 6.23. S. mentella in subareas 1 and 2. Diagnostic plots for the demersal fleet catch-at-age data. Top-left: scatter plot of observed vs. fitted indices. The dotted red line indicates a 1:1 relationship. Top-right: box plot of residuals (observed - fitted) for each age. Bottom-left: box plot of residuals for each year. Bottom-right: bubble plot of residuals for each age/year combination. Bubble size is proportional to mean residuals; blue bubbles are positive residuals and red bubbles are negative residuals.
