发帖数: 1290 | 13 有些时候文章中讲到 standard deviation 实际上指得是 mean 的 standard

怎么样才能区分清楚他们讲的到底是mena 的 standard deviation 还是样本的
standard deviation？
顺便请教一下，meta-analysis 中，inverse-variant weighted 方法用的是 1/(
standard variation of samples) 还是 1/(standard deviation of mean)？我觉得
应该是后者，因为这样即考虑了样本的方差，也考虑的样本的大小。不知是否理解正确？

There appear to be two different definitions of the standard error.
The standard error of a sample of sample size n is the sample's standard
deviation divided by sqrt(n). It therefore estimates the standard deviation
of the sample mean based on the population mean
这种有专门的称呼，是SEM。
The standard error of an estimate may also be defined as the square root of
the estimated error variance sigma^2 of the quantity,

底座：
我收到的standard program这款是6300型号，重量比750的底座要轻很多。
噪声：
standard program噪声大于750。
口感：
750细腻程度大于standard program。我做了两组对照实验，黄瓜胡萝卜汁，玉米汁。
都是用同一来源、同样份量的材料。虽然两者都还是能吃出渣，但750的细腻度体现在
口感非常轻盈，非常creamy。另外玉米汁的实验中，750肉眼看不到任何渣，standard

没想到 standard error 和 standard deviation 的定义在这个版上也会有争议啊。
比如一个服从标准正态分布变量的 standard deviation 就是 1。一个来自标准正态分
布的样本，如果把它的均数作为一个随机变量的话，它的 standard deviation 就是 1
/n^0.5，其中 n 为样本大小，对吧？那么这个均数的 standard deviation 也就是样
本的一个 standard error，对吧？由于样本均数是总体均数的一个 estimator，所以
我的理解是 standard error 就是 estimator 的deviation。
有些场合，比如meta-analysis 的文献中，很多提到用 inverse-variance-weighting
的方法。由于没有明确指明，我就不明白这个variance 用的是样本本身的variance，

如果是假设normal distribution, critical value = 1.96.
但是如果我假设estimate是服从一个复杂的分布，而critical value只能用bootstrap
