G0165 : Type mismatch or missing arguments Argument 2, found MATRIX , expected ??? (19) 'Argument 2, found MATRIX , expected ??? (19)'

Hi,

I have tried running the below code, but got this error, G0165 : Type mismatch or missing arguments Argument 2, found MATRIX , expected ??? (19) 'Argument 2, found MATRIX , expected ??? (19)' . Tq

The problem here is that the likelihood function required by maxlikMT takes different parameter inputs than the likelihood for maxlik. This code is set up to use maxlik and will not work for maxlikMT without some modification. If you change maxlikmt to maxlik and change maxlikmtprt to maxlikprt, the code should run without problem.
