In this study, fleets must own at least one truck that is not used for
emergencies. The data contain information on violations to road safety
(with convictions) committed by fleet owners between 1989 and 1998,
information describing the vehicle, vehicles' mechanical inspection
records, and the record of violations with convictions and demerit
points (for speeding, etc.) of drivers, as well as data on all
accidents involving a police report. These accidents include all
traffic accidents causing bodily injury and all accidents causing
material damage, reported by the police in Quebec.

The variables are described in the file "variable_def.txt". 

The file "hierarchical.SAS.txt" is a SAS program that maximizes the
log-likelihood function (eq. 5).

Both files are ASCII files in DOS format. They are zipped in the file
