gainFunction: Calculates the gain for one single value

In avilesd/productConfig: Tools to analyze behavioral patterns from Product Configurators

Description

Given the value of an attribute (v1) and the reference point of the same attribute (v2), calculates the gain and returns it [1,2]. It is not built as a stand alone function, rather as an object to be used by other major functions, such as gainMarix, lossMatrix.

Usage

gainFunction(v1, v2)

Arguments

v1	value of attribute j in round i
v2	reference point of attribute j

Details

For understanding how this works, see the function itself or refer to the paper. It handles only discrete numbers, so no interval numbers. Also a point to improve further on.

Value

gain, numeric value.
