| Oct 14, 2015 at 20:28 | comment | added | gappy3000 | Carlo, it makes sense but can you think of a counterexample? | |
| Oct 13, 2015 at 20:00 | comment | added | Carlo Beenakker | how can you exclude with exponentially small probability that $Y_i\approx -X_i$? I would expect a power law in $\epsilon^2$, not an exponential. | |
| Oct 13, 2015 at 19:43 | comment | added | Kevin P. Costello | I guess $c$ here is allowed to depend on the distribution of the $X_i$ somehow? (If not, what's preventing the $X_i$ from, say, each being $0$ with probability $1-\frac{1}{N^2}$). | |
| Oct 13, 2015 at 15:42 | comment | added | gappy3000 | Yes, I agree. I believe the RHS could be an even stronger $\exp(-cN\epsilon^2)$, but would be happy with the original conjecture. | |
| Oct 13, 2015 at 15:20 | comment | added | Fedor Petrov | in any case, $N$ must appear somehow in the inequality | |
