         startShift(model,data, y0=NULL)

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

   model: A TSmodel or object containing a TSmodel.

    data: A TSdata object.

      y0: initial condition ...

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

     For many time series models several starting data points are 
     required before output from the model can be calculated (or makes
     sense). This generic function extracts or calculates that  number
     of periods.

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

     An integer.

_N_o_t_e:

     There is some redundancy between this and startShift which  should
     be cleaned up.

_S_e_e _A_l_s_o:

     'TSmodel'
