One wants to subtract off the main term I've just described and measure the error term, I guess. But here the main term is a limiting probability distribution, not a limiting value as in the law of large numbers. So the error term could be the error in this probability distribution, but then it would not itself be a probability distribution. | |

| Jan 15, 2017 at 20:19 | comment | added | Will Sawin | At the highest scale, I think one can show the value distribution, rescaled by an appropriate power of $R$, converges as $R$ goes to $\infty$ to the value distribution of the leading term of $p$ on a ball of radius $1$. There shouldn't be any simpler characterization of this measure. | |
| Jan 15, 2017 at 15:53 | comment | added | Igor Rivin | @WillSawin I was intentionally vague. For example, a simple question would be whether the map is onto some interval $[-N, N].$ This is not true if the polynomial is, say a square, and presumably not if it's reducible (you are not going to hit many primes), but otherwise?! This is the "short scale" question, I assume. A simpler (I assume) question is: how many distinct values are assumed, and the easiest (as you say) is what does the probability distribution is like when you rescale (but I don't know the answer to even that). | |
| Jan 15, 2017 at 14:36 | comment | added | Will Sawin | What do you mean by how the variables are distributed? Presumably we know the distribution well on a large scale but not so well on a short scale. | |
