To whom may offer me help,

I would like to run "intreg" since my dependent variable is an interval from 0 to 90. However, the depvar is expressed in point data, not in interval format. See the screenshot:

Array
My intention is to create 9 interval categories:
- 1 (0 , 0)
- 2 (3 , 5.9)
- 3 (6 , 14.9)
- 4 (15 - 29.9)
- 5 (30 - 44.9)
- 6 (45 - 59.9)
- 7 (60 - 74.9)
- 8 (75 - 89.9)
- 9 (90 - 90)

or find an alternative way of running "intreg".

I would highly appreciate some help in this regard. Thanks in advance.

Antonio
