rabbits

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 &#8220;C&#8221;, low dose &#8220;L&#8221;, medium dose &#8220;M&#8221; 
 and high dose &#8220;H&#8221;. The animal species used in the experiment was banded Dutch rabbit (Paul, 1982, Table 1).

datasets

Provides a set of functions to analyse
overdispersed counts or proportions. Most of the methods are
already available elsewhere but are scattered in different
packages. The proposed functions should be considered as
complements to more sophisticated methods such as generalized
estimating equations (GEE) or generalized linear mixed effect
models (GLMM).
