Re:st: Overlay stcurve graphs from different models

[Ulrich Atz <ulrich.atz@students.uni-mannheim.de>]

Hello,

stcurve, hazard outfile(...) gives me a completely different output  
than using the predict hazard, haz command (weibull, exponential  
distribution). Why?
Consequently, line hazard _t looks differently than stcurve, haz

Thank you very much.
