Re: How Accurate Is Aggression Factor For Small Sample Sizes?
[ QUOTE ]
I would guess it is comparable to how accurate VPIP and pfr are over a small sample size

No, not at all. Or at least: there is no simple reason I see to think so. First of all, note that every hand played counts towared VPIP and PFR, wheras only hands where you see a flop count toward flop aggr, only hands where you see a turn count toward turn aggr, etc. So we should expect river aggr. to converge to its true value most slowly.
Also, note that aggr is a different kind of stat than a simple percentage stat. It's the proportion of bet/raise to call. So it may have a different kind of distriubtion than the binomial -- I can't think now what it would be.
In any case, I'm expecting the accuracty of these stats for small samples to be much lower than people give them credit for, but hoping they won't be.
