Dear Paul,
Thank you for your suggestion. I was moved by the fact that people are so
nice to help learners and ask for nothing.
With your help, I made some changes to my code and add more comments, try
to make things more clear.

I have 2 ideas for you.
1. Fit with lme4 package, using the lmer function. That's what it is for.
2. If you really want to write your own EM algorithm, I don't feel

here is my program... Im trying to fit 1 component to 6 components in each of
the 300 generated samples. Each sample has size=200. For each of the 300
generated samples and for each modeled component (v=1,2,3,4,5,6), I will get
estimates of the parameters that will maximize the likelihood, AND the

Thanks David. I already tried two different programs for this. The first one
has errors.
I'm working right now on my alternative program ( i hope it will work), BUT
I still prefer to use the first program I made because it is more detailed.
So, I'm trying how to correct the errors in the first R p

Hi Mike,
I have an EM algorithm code for a binary von Mises mixture with 5 parameters:
mixing proportion (p), 2 locations (m1, m2), and 2 dispersion parameters (k1,
k2). Of course, your model is nested within this one, where k1=Inf, m1 =
arbitrary, m2=0. You should be able to modify my code e

[1-Sp(i) ]^(t_ik ) (1-p)]
This is my observed loglikelihood. It is a sum over i (there are I tests)
and over k (K patients). t_ik is the result for the kth patient on the ith
test.
Se(i)= sensitivity, Sp (i)= specificity and

The EM algorithm is not an algorithm for solving problems, rather an
algorithm for creating statistical methods. So you need to look for a
package to solve the specific problem you want to solve.
In some engineering literature the term is used for its application to
