Fisher信息不等式与中心极限定理

Fisher Information inequalities and the Central Limit Theorem

Oliver Johnson, Andrew Barron

摘要:

给出了中心极限定理中Fisher信息和相对熵收敛速率为O(1/n)的条件.我们使用L2空间中的投影理论和庞加莱不等式,以更好地理解Barron和Brown的结果所隐含的Fisher信息的减少。我们表明,如果标准化的Fisher信息变得有限,那么它收敛到零。

英文摘要:

We give conditions for an O(1/n) rate of convergence of Fisher information and relative entropy in the Central Limit Theorem. We use the theory of projections in L2 spaces and Poincare inequalities, to provide a better understanding of the decrease in Fisher information implied by results of Barron and Brown. We show that if the standardized Fisher information ever becomes finite then it converges to zero.
