Dear R-Community, I'm writting my diploma-thesis this days. Therefore I have to estimate a few coefficients with a Survreg function (library=Survival). My Problem is that the estimated coefficients doesn't make sense. *My Questions:* - What role plays the scale-Value for the coefficient-estimation? - How can I interpret a scale-value like 3 or 12? - Why estimates R for some scales an Intercept and for some not? - Is it usual that the estimations differs so much (factor 10000) for different scale-Values? Thank you in Advance! :-) Best wishes, Stefan -- View this message in context: http://r.789695.n4.nabble.com/scale-Problem-in-Survreg-function-tp4653619.html Sent from the R help mailing list archive at Nabble.com.
