Figure 5. Simulation results.

(A) Histograms of estimates of the coefficients with simulated effort included as a new covariate from the model runs as described in ‘Sensitivity analyses’ subsection. The vertical dotted lines indicate the estimates obtained using the model that does not include simulated effort (see specific values in Table 1). Abbreviations are described in the main text. (B) Value of effort coefficient and 95% CI in each model run. This coefficient is statistically significant if the CI does not include zero.
