一般随机元期望泛函估计的渐近分布

Asymptotic distributions for estimated expected functionals of general random elements

Yasutaka Shimizu

摘要:

考虑一般随机元的期望泛函的估计问题,其值在度量空间中。如果该泛函是一个含有未知参数的显函数,我们可以通过在该函数中插入一个合适的估计量来估计它,并且我们可以找到渐近分布。然而,如果函数是隐式的参数,它会导致一个问题,指定渐近分布。本文给出了在泛函隐式于参数中时渐近分布的一般条件,并进一步研究了当随机元为半鞅时渐近分布的性质。

英文摘要:

We consider an estimation problem of expected functionals of a general random element that values in a metric space. If the functional forms an explicit function of some unknown parameters, we can estimate it by plugging-in a suitable estimator in to the function, and we can find the asymptotic distribution. However, if the functional is implicit in the parameters, it causes a problem of specifying asymptotic distribution. This paper gives a general condition to specify the asymptotic distribution even if the functional is implicit in the parameters, and further investigates it in detail when the random elements are semimartingales.
