Description

1985 Auto Imports Database.
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.

%    -- Kibler,~D., Aha,~D.~W., \& Albert,~M. (1989).  Instance-based prediction
%       of real-valued attributes.  {\it Computational Intelligence}, {\it 5},
%       51--57.
%          -- Predicted price of car using all numeric and Boolean attributes
%          -- Method: an instance-based learning (IBL) algorithm derived from a
%             localized k-nearest neighbor algorithm.  Compared with a
%             linear regression prediction...so all instances
%             with missing attribute values were discarded.  This resulted with
%             a training set of 159 instances, which was also used as a test
%             set (minus the actual instance during testing).
%          -- Results: Percent Average Deviation Error of Prediction from Actual
%             -- 11.84% for the IBL algorithm
%             -- 14.12% for the resulting linear regression equation

% 4. Relevant Information:
%    -- Description
%       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.
%

%             "class" attribute.
