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

     Extracts the hyper-parameter estimates from a 'gagafit' object and
     puts them in a list.

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

     getpar(gg.fit)

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

  gg.fit: Object of class 'gagafit', as returned by 'parest'. 

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

     This routine simply evaluates the component 'gg.fit$parest' from a
     'gagafit' object, which causes an error if this component is not
     available. This routine is used internally by a number of other
     routines.

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

     A list with components: 

     a0 : Estimated value of hyper-parameter 'a0'

     nu : Estimated value of hyper-parameter 'nu'

 balpha : Estimated value of hyper-parameter 'balpha'

nualpha : Estimated value of hyper-parameter 'nualpha'

probclus : Estimated cluster probabilities

probpat : Estimated prior probability of each expression pattern

     microarray data analysis. <URL:
