freight

A set of data on airfreight breakage. Data are given on 10 air shipments, each carrying
1000 ampules of some substance. For each shipment, the number of ampules found broken upon arrival, and the number of times the shipments were transferred from one aircraft to another, are recorded.

datasets

Inference in mixed-effect models, including generalized linear mixed models with spatial
correlations and models with non-Gaussian random effects (e.g., Beta Binomial,
or negative-binomial mixed models). Variation in residual variance is handled and can be modelled
as a linear model. Various approximations
of likelihood or restricted likelihood are implement, in particular h-likelihood and Laplace approximation.
