| Aug 11, 2015 at 13:48 | comment | added | Suvrit | Ok, I just read the "where M is any median..." part in the paper, and thought it should be easy to extrapolate. But as you say, maybe not! Though is it $\|E X\|$ or $E \|X\|$, or both? | |
| Aug 11, 2015 at 12:56 | comment | added | Hedonist | Suvrit: It appears this paper too deals with the question of how concentrated $||X||$ is to its median. I am interested in showing it is close to $||\mathbb{E}X||.$ This will need some stringent constraint on the tails of the entries, and will not happen under such minimal assumptions as in the paper you provide. | |
