In this exercise you will:
Investigate the car insurance claims data, used by McCullagh & Nelder (1989). Obtain the data using:
Your task is to model the average claims (AveClaim
) for
damage to an owner’s car on the basis of the policy holder’s age group
(AgeGroup
1-8), the vehicle age group
(VehicleAge
1-4), and the car group (CarGroup
1-4). Be sure you check if any of the two-way interactions are
significant.
Hint use glm with family=Gamma() and link="inverse"
You should compare your work with the solutions for this workshop.
