Outline of Final Research Achievements

Resampling methods are designed in order to obtain approximated distributions of statistics by means of repeated sampling from the empirical distribution based on a sample from a population. Despite the frequent use to small size samples, only their asymptotic aspects for infinity in size have been discussed, excluding the reports on numerical experiments.
The main target of this research is to represent the characteristics of the resampled empirical distributions exactly, from the perspective that resampling is to sample a weight vector given to observation vector. The moments that characterize the distribution of the moments of the resampled distribution (moments-of-moments) have been written in terms of the moments of the original sample and the weight distribution; the moments-of-moments-of-moments are also obtained in terms of the population moments and the weight moments. The results seem useful for comparison between existing methods and for generation of new ideas.
