谁能解释一下sampling, permutation, bootstrap之间的异同？

回复 第1楼 的 ruikoeln：其实wiki一下就知道了。BOOTSTRAP的话统计本科也不会很懂。SAMPLE是抽样，permutation就是组合，是高中学过的。

nonparametric bootstrap = using multinomial sampling from a sample to mimic the original sampling procedure;

permutation = either considered as a group theory based testing; or considered as conditioning on a minimal sufficient statistic;

sampling = obtaining a subset from a population.
