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

     Compute degrees of freedom for wavelet thresholding model.

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

     dof(wd)

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

      wd: The wavelet object

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

     The wavelet thresholding is a non-linear transform and 'dof'
     returns the approximate number of degrees of freedom.

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

     The number of degrees of freedom.

_R_e_f_e_r_e_n_c_e_s:

     see 'wd' for a list.

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

     'threshold'

     example(wd)
     threshy <- threshold(wds)

     # Compare degrees of freedom
     dof(wds)        # 1024
     dof(threshy)    # about 23
