如何将 plot a 累积分布到 R

Question

enter image description here

Currently, I am asked to plot the cumulative distribution in R. I have no idea how to go about it. Can anyone help me out here?

Answer 1

you have a discrete distribution you can write it out and don't need ecdf() Note I am using the percentages from the figure you posted in the question. you can also write this as a function if you case become more complicated but I started here.

val <- c(0 , 1/10, 1/10,1/10,3/10, 3/10, 6/10,6/10, 10/10)

x <- 0:8


yz <- data.frame( x=x,val = val)


plot(yz$x, yz$val)
