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 useful.
My question is:
In the Surv object you have two arguments, "time" and "event". I have
two events, namely withdrawn and success.
Does coxph function calculate the coefficients correctly when you put no
"event" argument into the Surv object?
Thus:
Coxph(Surv(duration)~covariates,data=data) duration=duration of the deal
Best regards,
Sharon Mazurel
