I'm assuming that English is not your first language. In light of that, I
would suggest that you post your question in a language that we both
speak: R. Please include:
1) E-step and M-step functions.
2) The proposed optim/maxLik call.
Mostly because (at least optim) does not have a parameter called
"limiter".
