orob1

Data describing the germination for seed Orobanche cernua cultivated in three dilutions of a bean root extract (Crowder, 1978, Table 1). The mean proportions of the three groups are 0.142, 0.872 and 0.842, and the overall mean is 0.614.

datasets

Provides functions to analyse overdispersed
counts or proportions.  These functions should be considered as
complements to more sophisticated methods such as generalized
estimating equations (GEE) or generalized linear mixed effect
models (GLMM). aods3 is an S3 re-implementation of the
deprecated S4 package aod.
