added trace condition
|
| Nov 23, 2015 at 16:19 | comment | added | Arnold Neumaier | My $G$'s are certain parametric matrices of arbitrary dimension. The trace of $G$ is zero; so the second-moment method gives no result. | |

added real needs

| Nov 23, 2015 at 16:17 | comment | added | Yoav Kallus | Well, the quality of the bounds will depend on what your $G$ is. If you don't have a specific $G$ in mind, then it would depend on what your requirements for "good" are. Try it and let us know if it is sufficient. | |
| Nov 23, 2015 at 16:12 | comment | added | Arnold Neumaier | Only if one can deduce from them good bounds on the probabilities. | |
| Nov 23, 2015 at 16:07 | comment | added | Yoav Kallus | Are moment bounds sufficient? (e.g. en.wikipedia.org/wiki/Second_moment_method) | |
