Note that levelsof factor, local(fac_lev) foreach i of local fac_lev { gen ydf`i' = cdf if factor==`i' } is pretty much equivalent to separate cdf, by(factor) gen(ydf) Nick n.j.cox@durham.ac.uk sjsamuels@gmail.com To plot multiple KM curves on the same graph by levels of some factor, create a separate variable for each with something like: ******************************************* sts gen surv = s, by(factor) gen cdf =100*(1-surv) **************************************************** * Create a separate CDF for each factor level **************************************************** sort factor outcome levelsof factor, local(fac_lev) foreach i of local fac_lev { gen ydf`i' = cdf if factor==`i' } twoway scatter ydf* outcome if cdf<= 0.5 , // Add remaining options below On Mon, Aug 31, 2009 at 11:27 AM, <sjsamuels@gmail.com> wrote: > -- > The only solution that I've found to this problem is to generate the > the failure curve (1 - the survival curve), using -sts gen- and then > to use -twoway- with an -if- clause to limit the range and a > "connect" option to connect the points. > -Steve > > On Mon, Aug 31, 2009 at 7:37 AM, Philip Ryan<philip.ryan@adelaide.edu.au> wrote: >> sts graph...., .... ylabel(0(.1).5, ang(hor) nogrid)..... >> >> Phil >> >> -----Original Message----- >> From: owner-statalist@hsphsun2.harvard.edu >> [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Fiona Bruinsma >> Sent: Monday, 31 August 2009 10:00 PM >> To: statalist@hsphsun2.harvard.edu >> Subject: st: Decrease range of y axis >> >> Hi, >> >> I am creating a graph of a kaplan-meier curve.
