Is there any way of saving the data used to generate the Kaplan-Meier
survival curve when using -sts graph-?
I have two survival curves with the probability of not developing leg
ulcers. My time variable is time to ulcer (in months). How can I
reverse the survival curves so that we would have the probability of
developing leg ulcers?
--------------------------------------------------------------------------------
See the help file for -sts-, the parent command for -sts graph-.
(Type -help sts-.) In particular, take a look at the passages for -sts
generate-. (Also, type -help sts generate- or click on the hyperlink from
within the viewer while displaying the help file for -sts-.)
Assuming that the probability of not developing leg ulcers by X months + the
probability of developing leg ulcers by X months sums to 1.0, it shouldn't
be too much trouble to plot the failure curve.
