For simple bets with two outcomes, one involving losing the entire amount
bet, and the other involving winning the bet amount multiplied by the payoff
odds, the Kelly bet is:
f* = (bp-q)/b
where:
f* is the fraction of the current bankroll to wager;
b is the net odds received on the wager (that is, odds are usually quoted as
"b to 1")
p is the probability of winning;
q is the probability of losing, which is 1 − p. | I***e 发帖数: 1136 | 2 it optimizes expected log return.
