Hi statalisters,

I fitted a Cox PH model saving the baseline survivor function:

. stcox x1 x2 x3 ,  basesurv(bsur)

Then I estimated a survival curve at some specific values of my covariates:

. stcurve ,sur at(x1=0.12 x2=0.69 x3=1.7) outfile(plot_values)

Here's my question: I need to produce the values used to plot these
curves for each individual "i" by taking account of their specific
information (x1i, x2i, x3i). Is there anyway to do this?

Or can someone please explain me how do stcurve get these values? I
had no success finding the formula

Thank you very much
