Thanks as always to Kit Baum, a new version of the kmest package is now available for download from SSC. In Stata, use the ssc command to do this, or adoupdate if you already have an old version of kmest.
The kmest package is described as below on my website. The new version adds a centiles() option, enabling the user to estimate Kaplan-Meer percentiles as well as (or instead of) Kaplan-Meier survival probabilities. It also adds an option stransform() to specify a transformation for survival probabilities, and an option ctransform() to specify a transformation for percentiles.
Best wishes

TITLE
kmest: Compute Kaplan-Meier survival probabilities and/or percentiles as estimation results
DESCRIPTION/AUTHOR(S)
kmest is intended for use in a survival time dataset set up by stset.
It computes Kaplan-Meier survival probabilities (as computed by sts
generate) for a list of times (sorted in ascending order), and/or
Kaplan-meier percentiles for a list of percents (srted in ascending
order), and saves them as estimation results, without a variance
matrix. kmest is intended for use with the bootstrap prefix, or
possibly with the jackknife prefix, to create confidence intervals for
the Kaplan-Meier survival probabilities and/or percentiles, possibly
allowing for clustering and/or sampling-probability weighting.
