| Mar 6 at 9:43 | comment | added | Chris Sanders | @VezenBU I still have a lot more to learn about probability distributions. Great question overall! | |
| Mar 6 at 8:09 | comment | added | Vezen BU | Please see my update with @Sal's help. There are existing results on random walks. | |

MathJax comment: Norms are better typeset using \|; for example, $\mathbb{E} \| \sum X_j \|_2$ yields $\mathbb{E} \| \sum X_j \|_2$.

| Mar 6 at 5:42 | comment | added | Vezen BU | Yes! But seemingly that is a nontrivial problem. | |
| Mar 6 at 5:37 | comment | added | Chris Sanders | Ah sorry yes that was a mistake, but the point still remains that it is just a matter of $\mathbb{E}||\sum X_j||_2$ @VezenBU | |
