I'd say that a Kaplan-Meier curve, or any other representation
of the survival function, is defined to start at 1. No matter:
it sounds as if you might want a plot of the (cumulative)
distribution function. Among other possibilities there is a
program -distplot- dedicated to this. -search distplot- will
show locations.
