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

     Computes the mean square error and gradient for the global anova

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

     msecalc(eS, lam, alpha, lowessnorm)

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

      eS: Array data. must be exprSet type. 

     lam: A parameter for glog transformation 

   alpha: A parameter for glog transformation 

lowessnorm: TRUE, if lowess method is going to be used 

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

     The input argument, eS, must be exprSet type from Biobase package.
      If you have a matrix data and information about the considered
     factors, then you can use 'neweS' to conver the data into exprSet.
     Please see 'neweS' in more detail.

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

   msev : A vector which contains MSE and gradient of two parameters
