Dear stata list,

I am trying to create a simulation program in stata. In this simulation, I would like to generate random numbers arising in various ranges, for example numbers between 0 to10, 0 to15, 0 to 20, 20 to 10 etc for several variables e.g. x1, x2, x3, x4 etc. Using the uniform distribution random number generator I can generate random numbers 0 to 10, or 0 to 100 without any problem by doing something like:

gen x1=int(10*uniform())

How can I generate random numbers from other ranges, for example 15 to 35 and how can I do this for several variables at once for example 5 observation with three variables as shown below for random numbers 1 to 10, 8 to 15 and 10 to 25 respectively as shown below

ob    x1   x2     x3
1      3     12     21
2      9     8       18
3      0     10     11
4     10    10     25
5      4     14     19

Your help will be highly appreciated.

Best wishes,

Patrick
