Hi all,
I want to graph survivor function and hazard rates by
different groups. For instance:
sts graph, by(sexo)
but I need the lines of sexo=0 and sexo=1 be differentiated
not by colour but for different types of lines, like
continuous or spacing lines or another types that allow me
to understand the differences between both groups in a
white-black printing.
How can I do it?
Thnaks a lot,
Patricia
