See .help xtile, or look up xtile in the reference manual - I think that
will give you what you want.

If I understand your question, you would want to type:

xtile newvar=oldvar, nq(4)

I apologize for posting a basic question.

I am trying to generate a categorical variable from a continuous
variable. I  would like the category endpoints to be the 25% percentile,
the 50% percentile,  the 75% percentile, and the 100% percentile.

I can do this interactively by typing tabstat var, stats(p25, p50, p75,
max)  and then using the gen command to manually enter what the tabstat
command  output. However, I would like to automate the process. Does
anyone know the  code for this?

Any help would be much appreciated!!
