Subject   st: Fitting weibull to a survival curve
Date   Wed, 08 Jun 2005 20:13:19 +0200

I have several survival curves from medical papers, describing the follow-up time of patients on the x axis and the % survival on the y axis.
I need to fit a weibull model to this curves to summarize them with 2 parameters , a shape and a scale parameter.
How can be practically done in Stata.
I have to input the time variable and the % survival ?
It is possible to stset these data ?
How should the weibull command be written?
Thanks for help
