[R] Weights using Survreg

[Terry Therneau]

 Survreg produces MLE estimates.

 For your second question, don't know what you are asking.  Can you be
more specific and detailed?

---begin included message --
Do you know if the parameters estimators are MLE estimators?

One more question:
In my case study I have failures that occured on different objects that
have
different age and length, could I use weight to find the estimates of a
weibull law and so to find the probabilty of failure per unit of length
for
example?
