Standard error of standard deviation: bootstrap or theoretical results?
...rror of standard deviation of a
sub-block-sample (sample size 250). I take 100 this kind of
sub-block-sample, randomly. For these 100 subsamples, I use the following 3
methods to calculate the standard error of standard deviation:
1. From book "Handbook of applicable mathematics", Walter Ledermann (chief
editor) Volumn VI: Statistics, Part A, Lloyd, John Wiley & Sons.
Page 30-32:
var(S) = (mu4 - mu2^2)/(4 * mu2 * n)
mu4 = E(X - mu)^4, mu2 = E(X - mu)^2, S^2 = sum(X - mu)^2/n
The results are about: 0.00090
2. From http://davidmlane.com/hyperstat/A19196.html
The results are about 0.0...
