What is the numerical approximation method used to find maximum likelihood estimator from log-likelihood function in OpenMx?
2. How to deal with multiple estimators when you have to maximize log likelihood function here in OpenMx? Say profile likelihood or partial derivation (may not be the case).
3. Can some of you please provide me a document on how the OpenMx works on the maximization of log likelihood function to find MLE?
Thank you so much.
