Given X1,...,Xn ~ t_k(mu,sigma) student t distribution with k degrees
of freedom, mean mu and standard deviation sigma, I want to obtain the
MLEs of the three parameters (mu, sigma and k). When I try traditional
optimization techniques I don't find the MLEs. Usually I just get
k->infty. Does anybody know of any algorithms/functions in R that can
help me obtain the MLEs? I am especially interested in the MLE for k,
the degrees of freedom.
Thank you!
Barbara
