Model

The final dissimilarity model in this example has the following levels and specifications:

Likelihood model :

Poisson (log link function) Yk ~ Poisson (Ek,Rk)

Random effects model :

Localised CAR ~ N

Dissimilarity metrics :

Z.LUNG (using population count per unit area) { wkj | k ~ j }

Regression equation :

[1] "LUNG[OBS] ~ offset(log(LUNGEXP))" ln(Rk) =
