*I?m writing to ask you how can I do Survivals Curves using Time-dependent
*covariates? Which packages I need to Install?*

  This is a very difficult problem statistically.  That is, there are not many 
good ideas for what SHOULD be done.  Hence, there are no packages. Almost 
everything you find in an applied paper (e.g. a medical journal) is wrong.

Dear Terry,

just in case it does not make too much work to 
you, maybe you could give some references to 
examples of wrong applications in applied medical papers.

Thanks,
Heinz
