library(GoFKernel) x<-seq(0,1000,33) f <- function(x) pbeta(x, shape1=2, shape2=3) f.inv <- inverse(f,lower=0,upper=1) f.inv(.5)  0.3857168
I don't understand the result of the Code.
When I imagine the inverse function of
pbeta, then on the $x$-axis are the probabilities and on the $y$-axis are the values from the $x$-variable.
f.inv (.5) is equal to the median or isn't it?
So I expected a value from the $x$-variable more exact 495. What is the meaning of the result 0.3857168?
The documentation was not a great help.
