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

     Experimental data for analyzing the effect of an increasing dose
     of a compound on the proportion of live foetuses  affected. Four
     treatment-groups were considered: control "C", low dose "L",
     medium dose "M"  and high dose "H". The animal species used in the
     experiment was banded Dutch rabbit (Paul, 1982, Table 1).

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

     data(rabbits)

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

     A data frame with 84 observations on the following 3 variables.

     _g_r_o_u_p a factor with levels 'C', 'H', 'L' and 'M'

     _n a numeric vector: the total number of foetuses.

     _y a numeric vector: the number of affected foetuses.
