I can easily do systematic sampling from the equal interval sample like 1,2,3,4,5,6,7,8,9,........ But I didn't select through systematic random sampling form the unequal interval.

5 4 75 64-75
6 2 81 76-81 77
7 3 90 82-90
From the above data how can I select the number through the systematic random sampling in stata.
From the Ti (Cumulative frequency) have to chose three sample through systematic random.
How it is possible. Advanced Thank.
