Dear Stata Users,

thanks to Kit Baum a new version of -stcband- is 
available on the SSC Archive.

This command estimates and graphs the 
confidence bands for the survival function.
Note that the official 
package estimates and graphs the confidence intervals of the survival 
function, not the same as and probably less useful than the confidence 

The difference is well illustrated for example in the book of 
Klein & Moeschberger (Survival Analysis Springer 2003) and in the 
Applied Survival Analysis of Hosmer, Lemeshow and May (2 ed. Wiley 
In the new version the Hall-Wellner method becomes the default 
method (before the default was the equal precision), the confidence 
bands for the cumulative hazard function is also available and some bug 
(I admit) has been fixed.

For R users the package may be an 
alternative, but I prefer -stcband- 

As always, any comment and 
feedback will be gratly appreciated.

Best wishes.
