WebFor example, take a binary feature X and a binary target. Let's say the target has a mean of 0.10 when taken over the entire dataset. To analyze the feature X, I take the target mean for each group within feature X. mean (X=0) = 0.07 mean (X=1) = 1.15 In this way, I can observe the effect of a feature on the target.
