Modelling Fixed Odds Betting for Future Event PredictionChen, Weiyun, Li, Xin, Zeng, Daniel 06 1900 (has links)
Prediction markets provide a promising approach for future event prediction. Most existing prediction market approaches are based on auction mechanisms. Despite their theoretical appeal and success in various application settings, these mechanisms suffer from several major drawbacks. First, opinions from experts and amateurs are treated equally. Second, continuous attention from participants is assumed. Third, such mechanisms are subject to various forms of market manipulation. To alleviate these limitations, we propose to employ the classic fixed odds betting as an alternative prediction market mechanism. We build a structural model based on a belief-decision framework as the event probability estimator. This belief-decision framework models bettors' beliefs with mixed beta distributions and bettors' decisions with prospect theory. A maximum likelihood approach is applied to estimate the model parameters. We conducted experiments on three real-world betting datasets to evaluate our proposed approach. Experimental results show that fixed odds betting based prediction outperforms the reduced form models based on odds and betting results, and achieves a comparable performance with auction-based prediction markets. The results suggest the possibility of employing fixed odds betting as a prediction market in a variety of application contexts where the assumptions made by auction-based approaches do not hold.

Kurzové sázky jako jedna z forem patologického hráčství u adolescentů / Odds betting as a form of pathologic gambling among adolescentsDOKULIL, Ondřej January 2016 (has links)
The diploma thesis focuses on fixed-odds betting among male adolescents. In theoretical part, game as a whole life matter is explained, afterwards it aims closer to hazard game, especially fixed-odds betting. Regarding to children, multiple smaller studies, focused on risky behaviour on the internet and gambling, are introduced. Empirical part combines qualitative and quantitative approach. Interviews with betters jointly with the theory creates the base for hypothesises and questionnaire, which was distributed in five schools; three elementary and two high schools. Results of the empirical part are suggesting that adolescent boys have experiences with fixed-odds betting even though they are not of age. Frequently, the reason for betting is being involved in sport and the favourite form is on-line betting.
