Class COptQuestKrigMixedDistance

java.lang.Object

com.opttek.optquest.COptQuestKrigMixedDistance

All Implemented Interfaces:

IKrigDistance

Direct Known Subclasses:

COptQuestKrigMahalanobisDistance, COptQuestKrigNormalizedDistance

public class COptQuestKrigMixedDistance
extends Object
implements IKrigDistance

An shared implementation of KrigDistance that handles different types of variables: right now we handle locations and "default" which is just numeric. We can add categorical and hamming later This class just handles the definitions of types, specific implmeentation are handled int he subclasses
