The two bar graphs are titled “Permutation Importance Ranking” on the left and “S H A P Importance Ranking” on the right, each showing the relative importance of various factors. In the “Permutation Importance Ranking” graph, the factors are ranked from top to bottom as follows: “Warranty,” “Product Information Mismatch,” “Durability,” “Performance,” “Selling Price,” “Sales Rank,” “Reliability,” “Secondary Features,” “Logistics Service Quality,” “Primary Features,” and “After-sales Services.” In contrast, the “S H A P Importance Ranking” graph ranks the factors in a different order: “Warranty,” “Durability,” “Product Information Mismatch,” “Performance,” “Selling Price,” “Sales Rank,” “Reliability,” “Logistics Service Quality,” “Primary Features,” “Secondary Features,” and “After-sales Services.” A rightward arrow at the bottom of both graphs is labeled “More Important.” Both graphs agree that “Warranty” is the most important factor, holding the first position in both rankings. The size of the horizontal bars increases from the bottom to the top in both graphs, but the bottom four bars in the right graph are slightly shorter than the bottom four bars in the left graph. The middle four bars are slightly longer in the right graph than in the left graph. The top three bars are the longest in both graphs.Variable importance ranking. Source: Authors’ own creation
