_D_e_s_c_r_i_p_t_i_o_n:

     After finding (learning) posterior parameters, the mean (or mode)
     of the distributions are found and are used to update the local
     probability distributions

_U_s_a_g_e:

     postdist(nw) 
     postdist.node(nd,nw,vtype = "mode")

_A_r_g_u_m_e_n_t_s:

      nw: an object of class `network'.

      nd: an object of class `node'.

   vtype: a string, taking values "mode" or "mean" of the variance
          distribution.

_D_e_t_a_i_l_s:

     In the learning procedure, the `postdist.node' procedure is called
     to ensure that the `prob' property for each node is updated. The
     `prob' property is first set in `jointprior' and is then updated
     using `postdist' to update them in the learning procedures. The
     `prob' property is used by `savenet' for exporting a network to
     the `.net' format.

_V_a_l_u_e:

     an object of class `network' with updated `prob' properties for
     each node.
