_D_e_s_c_r_i_p_t_i_o_n:

     The 'Oxboys' data frame has 234 rows and 4 columns.

_F_o_r_m_a_t:

     This data frame contains the following columns:

     _S_u_b_j_e_c_t an ordered factor giving a unique identifier for each boy
          in the experiment

     _a_g_e a numeric vector giving the standardized age (dimensionless)

     _h_e_i_g_h_t a numeric vector giving the height of the boy (cm)

     _O_c_c_a_s_i_o_n an ordered factor - the result of converting 'age' from a
          continuous variable to a count so these slightly unbalanced
          data can be analyzed as balanced.


_D_e_t_a_i_l_s:

     These data are described in Goldstein (1987) as data on the height
     of a selection of boys from Oxford, England versus a standardized
     age.
