Assume that I have a vector x = c(1, 1, 3, 0, 4, 5, 4). I would like to ask if there is a function to generate the cdf of this data. My desire result is
x c.d.f
1 0 1/7
2 1 3/7
3 3 4/7
4 4 6/7
5 5 7/7
I tried function ecdf(c(1, 1, 3, 0, 4, 5, 4)), but I don't understand the resulted value of this function
Empirical CDF
Call: ecdf(c(1, 1, 3, 0, 4, 5, 4))
x[1:5] = 0, 1, 3, 4, 5
Could you please help me generate this c.d.f? Thank you so much!
ecdf returns a function. You get your desired output using
Fn <- ecdf(x)
out <- data.frame(x = knots(Fn), cdf = Fn(knots(Fn)))
out
# x cdf
#1 0 0.1428571
#2 1 0.4285714
#3 3 0.5714286
#4 4 0.8571429
#5 5 1.0000000
