[R] Maximum Likelihood Estimation and Optimisation

[Harold Doran]

Well, lm() produces an OLS solution, which are also MLE solutions for the fixed effects. I think this is an easy way, although maybe not the best. 

BHHH is a numerical approximation that can be used when a closed form solution is not available. It is less sophisticated than Newton-Raphson.

Is this helpful?

Hello,

I want to calculate a maximum likelihood funktion in R in order to solve for the parameters of an estimator. Is there an easy way to do this in R? How do I get the parameters and the value of the maximum likelihood funktion. 

More, I want to specify the algorithm of the optimisation above: BHHH (Berndt Hall Hall Hausman). Is this possible?

Thanks a lot for your help and best regards

Marc
