Re: st: re: line patterns within Kaplan Maier

[Michael McCulloch <mm@pinest.org>]

Thank you Kit for pointing out that help text. What I'm looking for, 
so far unsuccessfully, is guidelines on how to specify specific 
formulas for cline_options for specific values of A and B.

The cline_options formulas I specified below were successful for only 
the plot lines in which A==1 and B==1, or
A==0 & B==0.

However, but the other plot lines where
A==0 & B==1, or
A==1 & B==0.
remained a solid line in spite of my specification:

sts graph if stage==5, by(A B) lpattern(-) xtitle("Survival time in ///
months") l2title("Percent surviving") xmtick(0(10)150) ///
	lpattern("l" if A==1 & B==1) ///
	lpattern("--" if A==1 & B==0) ///
	lpattern("--" if A==0 & B==1) ///
	lpattern("--.#" if A==0 & B==0) ///
