[R] Full likelihood from survreg

2009-05-27 Thread Ullrika Sahlin
R users, I am making model selection with an accelerated failure time model using the command survreg within the library survival. As I want to compare models with different probability distributions I need to have the full likelihood. How can I find out what survreg generates: the full
