Description

Modified 1985 Auto Imports Database. This data set consists of three types of entities: (a) the specification of an auto; (b) its assigned insurance risk rating; (c) its normalized losses in use as compared to other cars.
File contents

% This data set consists of three types of entities:
% (a) the specification of an auto in terms of various characteristics;
% (b) its assigned insurance risk rating,;
% (c) its normalized losses in use as compared to other cars. 
% The second rating corresponds to the degree to which the auto is more risky than its price indicates. Cars are initially
% assigned a risk factor symbol associated with its price. Then, if it is more risky (or less), this symbol is adjusted by
% moving it up (or down) the scale. Actuarians call this process "symboling". A value of +3 indicates that the auto is
% risky, -3 that it is probably pretty safe.The third factor is the relative average loss payment per insured vehicle year.
% This value is normalized for all autos within a particular size classification (two-door small, station wagons,
% sports/speciality, etc...), and represents the average loss per car per year.
% - Note: Several of the attributes in the database could be used as a "class" attribute.
% The original data (from the UCI repository) (http://www.ics.uci.edu/~mlearn/MLSummary.html) has 205 instances
% described by 26 attributes :

% - The goal variable is "price"
% - All nominal attributes (10) were removed.
