Dear R-users,

The data that I want to treat refer to claims and a glm have been adjusted
to the it.

Now there are some calculations that I wanrt to do with the residuals and
estimations from the model. The glm model has variables that refer to the
fleet to wich the vehicle refers to and variables that refer to the vehicle
(CC, type of vehicle, weight, etc).

In that sense I need to calculate sums, like the ones that I attached again.

I am following the paper:*

"Experience Rating Schemes for Fleets of Vehicles" from Denise Desjardins,
Georges Dionne and Jean Pinquet
