Dear all,
I am running Stata 14 on Windows 8
I performed a Cox analysis.
The code are:
sysuse cancer, clear
replace drug=2 if drug==3
stcox drug age
stcurve, survival at1( drug=1 age=25 ) at2( drug=2 age=25 )
It is possible to test if these two curves are statistically different at an alpha level (two-tailed) of 0.05?
Many thanks for the attention
