Dear list,

I have a very simple question - that I havent been able to find the
answer to myself.

I have done a cox-regression analysis - but the reference groups of
some of the variables are wrong. Can I change the reference group in
the stcox command - or do I have to go back and categorize these
variables differently?

Thank you
