 Default Maximizer for the M-Step 
==================================

.. r-package:: EMfit
.. r-pkgversion:: 0.2
.. r-name:: Mstep.default

     Mstep.default

Description
===========

This function provides a standard Newton-Raphson maximizer of the complete data
log-likelihood.

Usage
=====

.. code-block:: r

   Mstep.default(psi, cpl_data, wPPr, ll_cpl, completeInfo, Jacobian, ...,
     maxiter = 25, eps = 1e-07, verbose = FALSE)

Arguments
=========

``psi``
   A numeric vector with starting values

``cpl_data``
   A data structure with complete data

``wPPr``
   A vector with (weighted) posterior probabilities

``ll_cpl``
   A function that computes the complete-data log-likelihood

``completeInfo``
   A function that computes the 'complete-data' information matrix

``Jacobian``
   A function that computes the Jacobian of the log-likelihood function

``...``
   Other argumets, passed on to ``ll_cpl``, etc.

``maxiter``
   Maximal number of iterations

``eps``
   Numeric; a criterion for convergence

``verbose``
   Logical; should an interation trace be displayed?

Value
=====

A paremeter value that maximizes the Q-function
