Marginal mean responses of performance measures for each level of categorical management covariates.

Ten performance measures are shown, and for each random forest analysis (10,000 trees, 5 covariates randomly sampled at each split) the three categorical covariates were included along with the numerical covariates shown in Figs. 3–6. For each analysis, marginal means are given for both levels of each covariate. ‘% diff’ indicates the relative difference between the two levels, calculated as the absolute difference in means between the two levels as a percentage of the span of the 95% confidence interval of all data for the performance measure.
