风险分析中的稳健贝叶斯方法
发布时间:2018-09-06 11:39
【摘要】:风险分析中贝叶斯方法在构建决策框架、估计风险分布及参数化模型等方面,相比传统方法有更强的适应性和灵活性,但同时也存在一定的弊端。稳健方法弥补了贝叶斯方法的部分局限,针对不确定性问题的分析表明,在缺少准确和完全的统计信息时,稳健贝叶斯方法能够给出更加可靠的推断。
[Abstract]:In risk analysis, Bayesian method has more adaptability and flexibility than traditional methods in constructing decision framework, estimating risk distribution and parameterized model, but it also has some disadvantages. Robust method makes up for some limitations of Bayesian method. The analysis of uncertainty problem shows that robust Bayesian method can provide more reliable inference in the absence of accurate and complete statistical information.
