Thank you for your reply, it has been helpful. 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?
