Recently I attended an interview in which the interviewer asked a question which I do not know how to approach. Can anyone help me with this?
Q. Let’s say you have a Linear regression model create for a customer. You show it to the customer and relevant significant features. But customer asks you to add one more feature to this model as customer thinks this feature is very important, but according to model this feature is not significant. What will you do? How will you add this feature to the model?
