When a set of variables is intrinsically correlated, cokriging is equivalent to kriging for each variable, if all variables have been measured at all sample locations. For a particular variable in a given data set in the isotopic case, cokriging can be equivalent to kriging, even if the variable set is not intrinsically correlated. This is examined in detail in this chapter.
