大偏差界的两个非正则扩张

Two non-regular extensions of the large deviation bound

Masahito Hayashi

摘要:

我们制定了两种类型的推广的大偏差理论在一个非正规设置由Bahadur发起。一个可以看作是点估计的一个界,另一个可以看作是区间估计的一个界的极限。两者在规则情况下重合,但在非规则情况下不一定重合。利用相对Renyi熵的极限,导出了它们的上界,并给出了两个上界重合的充要条件。我们还表明,这两个界限在几个非正规的位置移动家庭的可达性。

英文摘要:

We formulate two types of extension of the large deviation theory initiated by Bahadur in a non-regular setting. One can be regarded as a bound of the point estimation, the other can be regarded as the limit of a bound of the interval estimation. Both coincide in the regular case, but do not necessarily coincide in a non-regular case. Using the limits of relative Renyi entropies, we derive their upper bounds and give a necessary and sufficient condition for the coincidence of the two upper bounds. We also show the attainability of these two bounds in several non-regular location shift families.
