Hello everybody,
I have a big problem that I do not manage to solve !
I will be very grateful if you can solve this !

I want to fit a t Copula with the copula package :

> student.cop <- ellipCopula("t", param = c(0.5, 0.6, 0.7), dim = 3, dispstr = "un",df=5)
> x<-rcopula(student.cop,1000)
> fit <- fitCopula(x, student.cop, c(0.5,0.5,0.5,5))

And there is an error for the optimization.

Thanks a lot if you respond to me !
Pierre.
