st: inverting the failure function

[burkom@comcast.net]

I am a STATA 7.0 user with a question on survival data.  I�ve been making failure function tables with commands like:

   

    sts list, by(covariate) failure at(1 2 to 10) compare

 

I would like to invert these failure functions using STATA.  In particular, I�d like to find the interpolated (or at least the nearest) times at which the failure function crosses each of a set of levels, say 0.5, 0.6,�,1.0 for each of the many values of covariate. 

 

Ideally, I�d like to get this table into a comma-separated text file such as outsheet can produce.  Is there a convenient way to put the table into such a file?

 

Thanks very much for any ideas,
