Maximum likelihood
Hello all, I'm trying to calculate the Maximum likelihood of individuals to get the ancestry. I mixd 3 populations 15 generations in proportion of 20% 20% 60% when each population sorce have diferent genome (0 1 and 2) with frequencies for each one. So now i have individuals looks like 0 0 2 1 1 2 0 ..... and i don't now how to calculate the mle although i try to figure out from the package st...

This solution does not seem to be portable to R or at least I do not realise how. Is there anyone who a) knows how one could make the MASS-method run under
