Dear R users, I am trying to find out what the function survReg does exactly with the Weights parameters. I looked in Terry Therneau documentations and other places and couldn't find anything. I tried to make an analogy with weighted OLS and assumed that the scale parameter Sigma in the accelerated failure-time model log(Time)= X*betas +Sigma*E, is of the form Sigma(i) = Sigma/Weights(i).
Can anyone confirm that or point me in the direction where I can find out for sure? Thank you, Sasha ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
