Optimal betting fraction
WebSep 1, 2024 · I would argue that the optimal initial betting is 2 − 2 2 ∼ 0.29. To do so, we need a few arguments: Whatever the initial bet is that you use to go from 0 to + 1, the second bet will be the same. Suppose not. Let x be the bet you made to go from 0 to + 1, and let y be the bet you make to go from + 1 to + 2, with y = x + ϵ where ϵ > 0. In a study, each participant was given $25 and asked to place even-money bets on a coin that would land heads 60% of the time. Participants had 30 minutes to play, so could place about 300 bets, and the prizes were capped at $250.

Web3 Development of modified Kelly criteria. We take the view that the determination of the optimal wagering fraction f is a statistical problem where the probability p of placing a winning wager is an unknown parameter. From the framework described in Section 2, we know that the Kelly criterion k(p) is the optimal value of f.Hence, the problem is one of …
