[英]Split continuous variable into equal size groups
我有一個連續變量Total_testscore 。 我將其分成 4 組，但它們的樣本量不同。 如何拆分變量以使變量的結果水平具有相同的樣本量？
> mydata$Total_testscore_f <- cut(mydata$Total_testscore, breaks = 4)
> table(mydata$Total_testscore_f)
(1.99,5.5] (5.5,9] (9,12.5] (12.5,16]
25 116 95 50
您可以使用quantile()函數來獲得所需的休息時間。 例子：
> x <- rnorm(100) # replace with your real data
> table(cut(x, breaks = quantile(x, seq(0, 1, l=5)), include.lowest = TRUE))
[-2.07,-0.756] (-0.756,0.0664] (0.0664,0.963] (0.963,2.83]
