How do Nonlinear Equations (NLE) and Maximum Likelihood (MAXLIK) differ?
A. Nonlinear Equations can be used to solve maximum likelihood problems by solving the normal equations rather than minimizing the log-likelihood. However, Nonlinear Equations does not have procedures enabling data set handling or statistical inference. You would have to provide these yourself. Maximum Likelihood has data set handling and statistical inference procedures built into it. Neither Nonlinear Equations nor Maximum Likelihood can handle constrained problems.
