Shapley value regression model
WebbThe Model_Year variable value is 76 or 77 for these three points, and the value for the third query point is 70. According to the Shapley values for the four query points, a small Model_Year value leads to a decrease in the predicted response, and a large Model_Year value leads to an increase in the predicted response compared to the average. Webb18 okt. 2016 · A key driver analysis tells you the relative importance of predictor (independent) variables on your outcome (dependent) variable. For example, a KDA can tell you which has a higher impact on customers’ likelihood to recommend: the price, quality, or usability. These are expressed using standardized values called beta weights (see #5).
