Ranked Column Contributions

Note: Because this analysis is based on the Bootstrap Forest method that has a random selection component, your results can differ slightly from those in Figure 25.2. See Bootstrap Forest.

The columns are sorted and ranked in order of contribution in the bootstrap forest model. Predictors with the highest contributions are strong candidate predictors for the response of interest.

Tip: Click on a column heading to change how the columns are sorted in the table.
