More playing around with R. To create the graph above, I sampled 100 times from two different normal distributions, then plotted the ratio of times that the first distribution beat the second one on the y-axis. The second distribution always had a mean of 0, the mean of first distribution went from 0 to 4, this is plotted on the x-axis.
Here is my code:
1 2 3 4 5 6 7 8 9 10 11 |
AbeatsB <- function(a,b) { sum(a>b)/length(a) } x = seq(0,4,.001) y = c() for (i in x) { y = c(y,AbeatsB(rnorm(100,i),rnorm(100,0))) } plot(x,y,pch=".",cex=2,col="blue") |
