comment Are the entries in matrix/vector product independent
Yes but your argument makes no reference to that. It would seem to apply equally to the $0,1$ case. What is it about $\pm 1$ that is making the difference?

Not so fast! If the vector $v$ had values which were $0$ or $1$ the $y_i$ would not be independent. If you knew, for example that the first half of the $y_i$'s were $0$ it would be a good guess the next half has plenty of $0$s in it too.

comment How to use the generating function $F(x) =x/(1-x-x^2).$
I simply took the third derivative of $x/(1-x-x^2)$ by hand. This is $6(x^4 + 6 x^2 + 4 x + 2)/(x^2+x-1)^4$.

If it can be shown that the smallest absolute value is $1/n$ that would be great.

A square matrix whose values are either $0$ or $1$.

comment How to find a confidence interval for a Maximum Likelihood Estimate
Well yes but let's assume only my cousin gets books for the moment. I still don't know how to solve that simplified version.

comment Smallest constant in exponent so that limit of sum is $0$
If you allow a=0 in the outer sum then the limit is 1 I think. You can't allow both a and b to be zero.
