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

     Computes the  ratio Observed/Expected under complete independence
     with margins of the multiple contingency table (in frequencies)
     and gives 'chi2' statistic of lack of complete independence.

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

      FCAmet(X,chi2=FALSE,E=NULL)

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

       X: a multiple contingency table (array) of order _k_

    chi2: if 'TRUE' prints the chi2 statistic information 

       E: if not 'NULL' represent a model which would be used for an
          'FCAk' relatively to a model

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

     a list with 

    data: an array '(X/count (-E))/Indepen' where 'Indepen' is the
          array obtained from he products of the margins

     met: a list wherein each entry is the vector of the corresponding
          margins i.e. 'apply(X,i,sum)/count'

   count: is the total sum 'sum(X).'

_N_o_t_e:

     The statistics and metrics do not depend on 'E'. The statistic
     given measure only the lack of independence.
