“Data for our third example were compiled by Margolin et al. (1981) from an Ames Salmonella reverse mutagenicity assay. Table 1 shows the number of revertant colonies observed on each of 3 replicate plates tested at each of 6 dose levels of quinoline.” (Breslow, 1984, Table 1).
“Weil (1970) in Table 1 gives the results from an experiment comprising two treatments. One group of 16 pregnant female rats was fed a control diet during pregnancy and lactation, the diet of a second group of 16 pregnant females was treated with a chemical. For each litter the number n of pups alive at 4 days and the number x of pups that survived the 21 day lactation period were recorded.” (Williams, 1975, p. 951).
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 2 x 2 factorial experiment comparing 2 types of seed and 2 root extracts. There are 5 or 6 replicates in each of the 4 treatment groups, and each replicate comprises a number of seeds varying between 4 and 81. The response variable is the proportion of seeds germinating in each replicate.” (Crowder, 1978, Table 3).
[Data describing the germination] “for seed Orobanche cernua cultivated in three dilutions of a bean root extract. The mean proportions of the three sets are 0.142, 0.872 and 0.842, and the overall mean is 0.614.” (Crowder, 1978, Table 1).
Unpublished laboratory data on the proportion of affected foetuses in two groups (control and treatment) of 10 pregnant female mice (Kupper and Haseman, 1978, p. 75).

A Comparison of Site Preferences of Two Species of Lizard
“These data describe the daytime habits of two species of lizards, grahami and opalinus. They were collected by observing occupied sites or perches and recording the appropriate description, namely species involved, time of the day, height and diameter of the perch and whether the site was sunny or shaded. Time of the day is recorded as early, mid-day or late.” (McCullagh and Nelder, 1989, p.129).

Mortality of Djallonke Lambs in Senegal
Field trial to assess the effect of ewes deworming (prevention of gastro-intestinal parasitism) on the mortality of their offspring (age < 1 year). This data set is extracted from a large database on small ruminants production and health in Senegal (Lancelot et al., 1998). Data were collected in a sample of herds in Kolda (Upper Casamance, Senegal) during a multi-site survey (Faugère et al., 1992). See also the references below for a presentation of the follow-up survey (Faugère and Faugère, 1986) and a description of the farming systems (Faugère et al., 1990).
cohorts
(Package: aod) :
Age, Period and Cohort Effects for Vital Rates
Number of prostate cancer deaths and midperiod population for nonwhites in the USA by age and period. The cohort index k is related to age and period indices (i and j, respectively) by k = j + I - i, where I = max(i) (Holford, 1983, Table 2).
