regression as feature importance Because Many off-the-shelf linear regressor returns p-value for each coefficient, many practitioners believe this for L Inear models, the bigger the absolute value of the coefficient, the more important the corresponding feature is. Rarely true as (a) changing the scale of the variable changes the absolute value of the coefficient (b) if feature S is multi-collinear, coefficients can shift from the one feature to others. Also, the more features the data set have
