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

     A data frame giving a series of measurements for the blood iron
     concentration of 55 anaemia female patients  based on the serum
     ferritin concentration, percent transferrin saturation and total
     iron binding capacity.

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

     data(blood)

_F_o_r_m_a_t:

     This data frame contains the following 3 variables:

     '_S_e_r_u_m' blood iron concentration measured by the serum ferritin
          concentration,  considered as the gold standard

     '_T_I_B_C' blood iron concentration measured by total iron binding
          capacity

     '_T_S' blood iron concentration measured by percent transferrin
          saturation
