问题如下:
Compared with bootstrap resampling, jackknife resampling:
选项:
A.
is done with replacement.
B.
usually requires that the number of repetitions is equal to the sample size.
C.
produces dissimilar results for every run because resamples are randomly
drawn.
解释:
B is correct. For a sample of size n, jackknife resampling usually requires n repetitions.
In contrast, with bootstrap resampling, we are left to determine how many
repetitions are appropriate.
c为什么不对。。。。
