Dec 17, 2013 at 14:04 comment added ofer zeitouni 1) range is 1...r (i.e. I do not look at r+1 component, which is determined by the others. You can take 1,..., (r+1), it's the same event). 2) No; I mean Binomial RANDOM VARIABLE (n, 1/(r+1)); this means, with n attempts and probability of success equal 1/(r+1).
Dec 17, 2013 at 13:16 comment added Dylan Pizzo Does that mean that $A_n$ should be with $j$ ranging from 0 to r if the vectors have r+1 components? (same for $j'$ as well except going from 0 to $j$)? Also, just trying to clarify, you say that $S_n$ is binomial(n,1/(r+1)); by that I assume you mean $\binom{n}{\frac{1}{r+1}}$?
Dec 16, 2013 at 16:59 comment added ofer zeitouni @Dpiz: When you say unit vectors of length r+1 with exactly one entry nonzero, you mean an r+1 dimensional vector with all components 0 except for one which is 1? Yes. What is $S_n(j)$? The $j$th component of $S_n$.
