st: RE: RE: Continous to categorical variable
Maybe I should describe a little bit better.
I do not want the variable to "become more like a normal distribution".
What I would like is the categories created to be such that the tails
contain less individuals, with an increase in the numbers as we get
closer to the middle category.
Thanks
Manos

For the latter have a look at -help egen- and look at the cut function.
For the former: how would you expect a variable to become more like a
normal distribution by making it coarser?
Hope this helps,
