Hello Statalist,

I need to generate a random variable from uniform distribution, but
the probabilities are not not same for each option. The variable is
discrete in interval [10,19] and is generated 10times. Each time one
of the options has twice as high probability of occuring as the
others. So in some sence, the draw is two-staged - in the first stage
a random number (n) between 1 and 10 is generated and then that
particular n-th option in the interval [10,19] has a probability 0.2
of occuring, the other options have a probability 0.8/9 each.

How can I generate such variable?
Thank you!!
Tomas
