Maxlikmt is a more advanced version of Maxlik. First, it uses a PV structure for parameters, and a DS structure for data. The PV structure allows you to store parameters in their original state, i.e., a matrix, or a vector, or symmetric matrix, and there is a method for specifying which elements are fixed and with are free parameters.

The use of structures means that the Maxlikmt run can be multi-threaded, i.e., you can run several of them at a time.

Also Maxlikmt allows for bounds on parameters.

Note:  MLMT is not backwards compatible.  If a user wants to run older code, they may need to use Maxlik 5.0.
