Estimates at each iteration
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".

[image removed] [R] Estimates at each iteration hello bye to: r-help 04/08/2011 11:45 AM Sent by: r-help-bounces at r-project.org Dear Sir\ Madam I am trying to maximise a complicated loglikelihood function via EM algorithm which consists of two step "E-step and M-step"and in this case I need to
maximize the expected of like lihood function " which I get from E-
step" and
take those estimates of parameter to update the E-step and repate these
till
convargence has been met. So I need to know if I control the number of iterlim in maxLik or optim Package by puting this number equals to one to
maximize
M-step and getting just the estimates of parameter for one iteration and hence use them to update the E-step and again maximaize M-step by using maxLik
or
optim by contoling the number of limiter and putting the number equals
to 1
is it true and acceptance? I mean if I do this my results can be reasonable?. please I am waiting your response. Regards Fauzia Taweab phd.student. [[alternative HTML version deleted]]
