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).
A data frame with 84 observations on the following 3 variables.
a factor with levels
a numeric vector: the total number of foetuses.
a numeric vector: the number of affected foetuses.
