[Chapter 2] How to calculate confidence intervals for MAE?

First of all thank you for creating wonderful book! I find it very well written and easy to follow.

My question is:
At page 80 there is a method for estimation confidence intervals for RMSE but not for MAE. I find MAE helpful too, because it is more easy to explain it to layman person than RSME. How can I estimate confidence intervals for MAE?

Thank you.

Start with Chapter 2, page 80, and the existing discussion of confidence intervals for RMSE. Determine how the book should explain estimating confidence intervals for MAE; done means a clear, correct method is documented alongside the RMSE material.
