可能重複:
R, correlation: is there a func that converts a vector of nums to a vector of standard units我可以用R計算z分數嗎?
通過閱讀計算器的評論,我發現,z分數可能與Python或Perl來計算的,但我沒有遇到任何的R呢。我錯過了嗎?可以用R來完成嗎?
由於(http://en.wikipedia.org/wiki/Standard_score。)
z-score = (x-μ)/σ
x is a raw score to be standardized;
μ is the mean of the population;
σ is the standard deviation of the population.
我相信我們有專門爲這個R封裝?我們可以在哪裏找到它們?或類似的正常化包?

Simon Blomberg:這是R.沒有if。只有如何。 - 'fortune(「simon blomberg」)' – 2011-06-07 10:26:04
爲什麼'pnorm(x,μ,σ)'是一個解決方案? – 2015-01-14 19:05:30
