统计推断中的几个信息不等式

Some Information Inequalities for Statistical Inference

Harsha K, Alladi Subramanyam

摘要:

本文首先描述了Naudts(2004)利用两类密度函数,即原始模型和护送模型得到的Cramer-Rao下界的推广概念.我们从统计的角度重新解释了Naudts(2004)的结果,并得到了一些有趣的例子,在这些例子中,我们得到了这个界。进一步,我们得到的信息不等式,推广了经典的Bhattacharyya界在正规和非正规的情况下。

英文摘要:

In this paper, we first describe the generalized notion of Cramer-Rao lower bound obtained by Naudts (2004) using two families of probability density functions, the original model and an escort model. We reinterpret the results in Naudts (2004) from a statistical point of view and obtain some interesting examples in which this bound is attained. Further we obtain information inequalities which generalize the classical Bhattacharyya bounds in both regular and non-regular cases.
