WitrynaAs expected, the maximum likelihood estimators cannot be obtained in closed form. In our simulation experiments it is observed that the Newton-Raphson method may not converge many times. An expectation maximization algorithm has been suggested to compute the maximum likelihood estimators, and it converges almost all the times. WitrynaThe Monte Carlo Newton-Raphson (MCNR) method is an iterative procedure that can be used to approximate the maximum of a likelihood function in situations where 掌桥科研一站式科研服务平台
