| Oct 24, 2020 at 23:27 | comment | added | Tan | @whuber Actually I had a mistake having the unnecessary $\mu = E(X)$ in the question. I guess this was what kjetil referred. | |
| Oct 24, 2020 at 15:55 | comment | added | whuber♦ | @Kjetil Because $\mu$ was a bound integration variable, there was no reason to change it to "$u$" and there was no ambiguity in its use (but I admit it was initially confusing to see it in the integral!) | |

| Oct 24, 2020 at 15:36 | comment | added | Tan | Thank you! I corrected it. | |
| Oct 24, 2020 at 14:38 | comment | added | kjetil b halvorsen♦ | You got an expression containing $\mu$. That can't be right, since the distribution of $| X-Y|$ do not depend on $\mu$. | |
| Oct 23, 2020 at 6:12 | comment | added | Tan | Thanks, @Xi'an. If there any further steps? I know how to derive this but not sure how to use it. I feel that it is even further than the hint in my question.. | |
