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).
