Finally, we used the variable importance scores, percent change in mean squared error (MSE), to identify loci that had the greatest influence on classification, by choosing those loci whose percent change in MSE was greater than 5%.
Using the estimated dietary content of Pacific herring eggs in scats as the response variable and ranking variable importance using percent increase MSE in the RF analysis, the top ranked predictor was averaged Pacific herring egg mass (16.6) followed by moderate predictors location (10.4), amphipod mass (10.3), and year (8.2) with day of the year as the lowest-ranked predictor (−4.6).
Proteins were grouped according to lifestyle, and for each functional role a percent importance value was calculated by summing the Gini importance scores for proteins in that functional role and dividing by the total number of proteins in all functional roles (Fig. 2).
The variable importance measures showing percent increase in MSE for each independent variable by each planning zone are summarized from Figs. 4, 5, 6, 7, 8, 9, 10, 11.
For 53% of all variables considered, the ratings of percent importance in the models were closer for the ANN and CE model than for MLR and CE.
Among these, the variable importance plot (VIP) and percent increase in mean squared error (MSE) provide relative importance of the independent variables in the prediction of the dependent variable.
Eighty-five percent see the importance of a good job to the life they want to lead, and the vast majority accepts responsibility for their own futures.
Thirty-seven placent place more importance on investigating Russia's role in the 2016 election, and 37percentt prioritize investigating the leaking of classified information to journalists.
Fifty-seven percent stressed the importance of service providers setting an example by not using tobacco.
In both rounds, the average ratings for importance were high: 75%and84%4% respectively (percent strongly agree, defined as a score of 6 or 7 on a 7-point scale); hence these results are not included in the Figures.
