Weights using Survreg
Dear R users,
I have been trying to understand what the Weights arguments is doing in the
estimation of the parameters when using the Surreg function.
I looked through the function's code but I am not sure if I got it or not.
For example, if I inclue the Surv function in it:
survreg(Surv(vector, status)~1,weights=vector2,dist="Weibull")
will it try to maximize the likelihood with
