[R] expression for simple EM

[Vumani Dlamini]

Dear R users,

I know this is the wrong forum for such a question but I need help.

I would like to write down the likelihood expression for a simple EM 
problem. I have one categorical covariate with 5 levels and a missing count 
which can fall in any of the categories. I know the solution to the problem 
but can't seem to get the likelihood expression correct (if it is possible).

Thanks.
