民意测验过程:模型研究与贝叶斯观点

Public opinion by a poll process: model study and Bayesian view

Hyun Keun Lee, Yong Woon Kim

摘要:

我们研究民意调查过程中,当前的分数是向公众开放的形成。投票者被假定为概率性地投票支持或反对他们自己的偏好,考虑到在得分中收集到的群体意见。民意测验得分的概率被发现遵循贝塔分布在大的民意测验限制。我们证明了各种民意调查结果,甚至矛盾的人口偏好是可能的非零概率密度,这种偏差很容易引发初始偏差。我们的投票模型可以用贝叶斯的观点来理解。

英文摘要:

We study the formation of public opinion in a poll process where the current score is open to public. The voters are assumed to vote probabilistically for or against their own preference considering the group opinion collected up to then in the score. The poll-score probability is found to follow the beta distribution in the large polls limit. We demonstrate that various poll results even contradictory to the population preference are possible with non-zero probability density and that such deviations are readily triggered by initial bias. It is mentioned that our poll model can be understood in the Bayesian viewpoint.
