A note on proving that the (modified) bootstrap works. (English) Zbl 0623.62041
Let $$X_ 1,...,X_ n$$ be i.i.d. random variables (rv’s) and let $$X^*_ 1,...,X^*_ m$$ be a bootstrap sample of i.i.d. rv’s with distribution function (df) $$F_ n$$, where $$F_ n$$ is the empirical df based on $$X_ 1,...,X_ n$$. Specifying $$m=m(n)$$ as some suitable function of n it is shown first that the bootstrap also works for the counter-examples given by P. J. Bickel and D. Freedman, Ann. Stat. 9, 1196-1217 (1981; Zbl 0449.62034).
Secondly, based on a result of W. Stute, Ann. Probab. 10, 86-107 (1982; Zbl 0489.60038) on the oscillation behavior of empirical processes a method is suggested which can be used to show that the bootstrap method of distribution approximation is asymptotically valid.
