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

     Pilot-Plant data from Daniel and Wood (1971). The response
     variable corresponds to the acid content determined by titration
     and the explanatory variable is the organic acid content
     determined by extraction and weighing. This data set was analyzed
     also by Yale and Forsythe (1976).
