problem with uniroot
Hi R-users,I'm trying to solve a non linear equation, to find the degrees of
freedom of a mixture of t student. I'm sure i wrote the minimization
equation in the right way, but when i try to run the EM algorithm to
estimate the parameters of the mixture, the following error will appear:
Error in uniroot(function(z) log(z/2) - digamma(z/2) + 1 - log((z + d)/2) +
:
f() values at end
