Z =（x-μ）/ σ μ为均值，σ为标准差。以下是R中将z-score转为p.value的方法：pnorm(q, mean = 0, sd = 1, lower.tail = TRUE)q就是z-score；个人最常用的是双边检验（two-tailed test).

One-tailed vs Two-tailed Tests of Significanceand reference #3 below. When obtaining a p-value from a z-score, it is important to choose the correct null hypothesis - one-sided or point null, depending on circumstances, and in most cases the correct p-value would be the one-sided / ...
To find the p-value that corresponds to a Z-score from a two-tailed analysis, we need to find the negative value of our Z-score (even when it’s positive) and double it. In the truncated Z-table below, I highlight the cell corresponding to a Z-score of -2.33. ...
The p-value calculator calculates the p-value for Z score, T score, F score and Chi-square score.If you don't have the score you may use one of the following calculators that will compute the score and the p-value:One sample Z-test, Two sample Z-test, One sample T-test,Two-Sampl...
Two-tailed Z-test: p-value=Φ(−∣z∣)+(1−Φ(∣z∣))p-value=Φ(−∣z∣)+(1−Φ(∣z∣)) From the fact that Φ(−z)=1−Φ(z)Φ(−z)=1−Φ(z), we deduce that p-value=2Φ(−∣z∣)=2(1−Φ(∣z∣))p-value=2Φ(−∣z∣)=2(1−Φ(∣z∣)...
