可能重复:
R, correlation: is there a func that converts a vector of nums to a vector of standard units我可以用R计算z分数吗?
通过阅读计算器的评论,我发现,z分数可能与Python或Perl来计算的,但我没有遇到任何的R呢。我错过了吗?可以用R来完成吗?
由于(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.
我相信我们有专门为这个R封装?我们可以在哪里找到它们?或类似的正常化包?

Simon Blomberg:这是R.没有if。只有如何。 - 'fortune(“simon blomberg”)' – 2011-06-07 10:26:04
为什么'pnorm(x,μ,σ)'是一个解决方案? – 2015-01-14 19:05:30
