Public Enumeration eDistanceMethods
Members| Member name | Value | Description | |
|---|---|---|---|
| eDFSquaredEuclideanFunction | 0 | Squared Euclidean - This distance is computed as: distance( x, y ) = sum ( xi - yi )^2 Squaring the simple Euclidean distance places progressively greater weight on objects that are further apart. | |
| eDFMaximumFunction | 1 | Maximum - This distance is computed as: distance( x, y ) = maximum( |xi - yi| ) This distance measure may be appropriate in cases when you want to define two objects as different if they differ on any one of the dimensions. | |
| eDFEuclideanFunction | 2 | Euclidean - Euclidean distance is simply the geometric distance in the multidimensional space. This distance is computed as: distance( x, y ) = sqrt( sum ( xi - yi )^2 ) | |
| eDFCityBlockFunction | 3 | City Block - This distance is computed as: distance( x, y ) = sum ( | xi - yi | ) In most cases, the city-block distance measure yields results similar to the simple Euclidean distance. Note, however, that the effect of outliers is dampened, since they are not squared. |
