2006-07-11 Thread Sharon.Mazurel
How can I model coxph() in combination with competing risks i.e. I have two events and for event the object will leave the data set. So : Coxph(Surv(time,event)~) the event is for all my objects 1. How can I model this? Sharon --

Dear Sir/Madam, My name is Sharon Mazurel and I'm busy with my final thesis about estimating the probability of the success or withdrawal of a merger or acquisition. For my model I also use duration analysis and found after doing some research that the coxph function in R is very
