Hello,
I am doing a cox regression and have a variable socioeconomic status 'ses' which I have labelled as 0= low ses, 1=middle ses, and 2=high. I would like to change my reference category from 'low ses' which is the default, to 'high ses' to enable easier interpretation and presentation of the results. I have used the command I normally use when doing a logistic regression char ses [omit] 2 but the reference category does not change afterwards. I use Stata Version 14.0. Can anyone kindly advise? Thanks.
