There is a set of objects to be classified into n classes. Each class has its own coefficient.

For example:

class      coefficient
 1             0.5
 2             0.7
 N             0.4

I arranged objects into classes and get the set of coefficients. But i need to determine a single coefficient that would be most suitable for the entire set of objects.

How can I Aggregate the Objects’ Coefficients and choose one common coefficient? Except for the methods of average coefficients.
