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

     Function to compute local regression bandwidths for local linear
     regression, implemented as a front end to 'locfit()'.

     This function is included for comparative purposes only. Plug-in
     selectors are based on flawed logic, make unreasonable and
     restrictive assumptions and do not use the full power of the
     estimates available in Locfit. Any relation between the results
     produced by this function and desirable estimates are entirely
     coincidental.

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

     regband(formula, what = c("CP", "GCV", "GKK", "RSW"), deg=1, ...)

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

 formula: Model Formula (one predictor).

    what: Methods to use.

     deg: Degree of fit.

     ...: Other Locfit options.

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

     Vector of selected bandwidths.
