社会系统中决策和信息流实证研究的Bootstrap方法

Bootstrap Methods for the Empirical Study of Decision-Making and Information Flows in Social Systems

Simon DeDeo, Robert X. D. Hawkins, Sara Klingenstein, Tim Hitchcock

摘要:

我们的特点统计引导估计的信息理论量的数据,特别是它的使用在大规模的社会现象的研究。我们的方法允许一个保存,大约,基本的公理关系的信息论-特别是,一致性下任意粗粒化-激励使用这些数量摆在首位,同时提供可靠性相媲美的贝叶斯估计的最先进的。我们展示了如何信息理论的数量允许严格的实证研究的决策能力的理性代理和时间不对称的信息流在分布式系统。我们提供说明性的例子,参考正在进行的合作工作,英国刑事法院系统的语义结构和当代阿富汗叛乱的冲突动态。

英文摘要:

We characterize the statistical bootstrap for the estimation of information-theoretic quantities from data, with particular reference to its use in the study of large-scale social phenomena. Our methods allow one to preserve, approximately, the underlying axiomatic relationships of information theory---in particular, consistency under arbitrary coarse-graining---that motivate use of these quantities in the first place, while providing reliability comparable to the state of the art for Bayesian estimators. We show how information-theoretic quantities allow for rigorous empirical study of the decision-making capacities of rational agents and the time-asymmetric flows of information in distributed systems. We provide illustrative examples by reference to ongoing collaborative work on the semantic structure of the British Criminal Court system and the conflict dynamics of the contemporary Afghanistan insurgency.
