Dear All
I would like to get the histogram for the following model with
discrete and continuous random variables:
* with probability 1/3, a random number is drawn from the continuous
uniform distribution (min=0, max=1);
* with probability 2/3, a random number is drawn from a different
continuous uniform distribution (min=-1/2, max=1/2).
Any help would be most welcome.
Thanks in advance,
Paul
My approach to generate the data would be
rMyfun - function(n){
  x1 - runif(n, 0, 1)
  x2 - runif(n, -0.5, 0.5)
  ifelse(rbinom(n, 1, 1/3), x1, x2)
}
Hope this helps,
Stephen
