非线性模型参数流形上精确置信区域的构造

Constructing Exact Confidence Regions on Parameter Manifolds of Non-Linear Models

Rafael Arutjunjan, Bjoern Malte Schaefer, Clemens Kreutz

摘要:

利用信息几何的数学框架,我们介绍了一种新的方法,它允许一个有效地确定确切的形状的同时置信区域的非线性参数化模型。此外,我们展示了如何逐点的模型预测周围的置信带可以构建从详细的知识,确切的置信区域,几乎没有额外的计算工作。我们使用宇宙学和流行病建模中的推理问题来验证我们的方法。一个开源的实现方案是公开的,通过InformationGeometry.jl包的Julia编程语言。

英文摘要:

Using the mathematical framework of information geometry, we introduce a novel method which allows one to efficiently determine the exact shape of simultaneous confidence regions for non-linearly parametrised models. Furthermore, we show how pointwise confidence bands around the model predictions can be constructed from detailed knowledge of the exact confidence region with little additional computational effort. We exemplify our methods using inference problems in cosmology and epidemic modelling. An open source implementation of the developed schemes is publicly available via the InformationGeometry.jl package for the Julia programming language.
