_D_e_s_c_r_i_p_t_i_o_n:

     Creates a link object based on the link function eta = mu^lambda.

_U_s_a_g_e:

     power(lambda = 1)

_A_r_g_u_m_e_n_t_s:

  lambda: a real number.

_D_e_t_a_i_l_s:

     If `lambda' is non-negative, it is taken as zero, and the log link
     is obtained.  The default `lambda = 1' gives the identity link.

_V_a_l_u_e:

     A list with components `linkfun', `linkinv', `mu.eta', and
     `valideta'. See `make.link' for information on their meaning.

_S_e_e _A_l_s_o:

     `make.link', `family'

_E_x_a_m_p_l_e_s:

     power()
     quasi(link=power(1/3))[c("linkfun", "linkinv")]
