Theoretical Separation

edit

The general identification equation

edit
 , where:[1]
  • Sj is the theoretical separatory value per jth characteristic,
  • C is the number of characteristics in the group,
  • V is the highest value of logic in the group and
  • j is the jth characteristic index in the target set, where:
j = 0..K and where:
  • K is the number of characteristics in the target set.

Minimal number of characteristics to result in theoretical separation

edit
 , where:[2]
  • tmin is the minimal number of characteristics to result in theoretical separation,
  • G is the number of elements in the bounded class and
  • V is the highest value of logic in the group.
